Chianan irrigation project
The first proposals for the dam were made as early as the 1930s during the Japanese occupation of Taiwan. The Japanese had built the Chianan Irrigation system to increase Taiwan's agricultural output, which was supplied primarily by the Zengwen River. Because the Zengwen River does not cross the area of the Chianan Plain to be irrigated, a tunnel had to be punched through mountains to divert Zengwen water into the Guantian River. Between 1920 and 1930, the Wushantou Dam was built, forming an...
Due to Taiwan's highly seasonal rainfall, the Zengwen River contains little water except during the wet season from May to October, during which massive floods occur that exceed the capacity of the diversion tunnel. Out of the average 1.6 cubic kilometres (1,300,000 acre⋅ft) annual flow of the Zengwen River, only 25 percent of the water could be effectively used. Furthermore, the Zengwen river has a high silt content, which was causing the Wushantou reservoir to quickly lose its capacity. In...
Construction finally began at the Lioutengtan site on October 31, 1967. Two tunnels were excavated through the rock underneath the south abutment of the future dam site. The outer diversion tunnel was 1,240-metre (4,070 ft) long and the inner diversion tunnel was 1,038-metre (3,406 ft). A rolled-earth embankment cofferdamwas constructed to divert the Zengwen River and protect the dam site from flooding, up to an elevation of 165 metres (541 ft).
The Zengwen reservoir receives its water from an extremely steep and rugged catchment basin of 481-square-kilometre (186 sq mi) in the Alishan Range of south-central Taiwan. The elevation of the land ranges from 227 metres (745 ft) on the shore of the reservoir to over 2,500 metres (8,200 ft) in the Alishan National Scenic Area near the summit of the range. About 77 percent of the watershed is forest, 13 percent is agriculture, 9 percent other uses and less than 1 percent is urbanized. The reservoir has suffered severe siltation (sedimentation) from the watershed, which has caused a large reduction in its capacity. Siltation has reduced the volume of water available for irrigation and hydropower, as well as reducing the effectiveness of the Zengwen reservoir to control flooding. The siltation rate has greatly increased in recent years, in part due to a sharp increase in the intensity of typhoon rains, as well as a rising frequency of drought. In August 2009, Typhoon Morakot caused m...
The Zengwen dam and reservoir are part of the Zengwen Reservoir Scenic Area.The reservoir was first opened to the public in July 1974.

The initial phase of the deal saw MediaTek taking a 48 percent stake, with an option to purchase th...
MediaTek's financial results have been subject to variation as the financial success of different product lines fluctuated. MediaTek's relatively strong sales in 2009/2010 was based on its strong market position for feature phone chipsets. Smartphone and tablet products contributed to MediaTek's sales and income increase in 2013, while revenue recognition from the acquisition of MStar Semiconductor, which became effective in February 2014, as well as a continuing strong position for smartphone and tablet solutions, were the main reasons for the sales growth seen in 2014.In 2014 smartphone chips accounted for approximately 50–55% of revenue, followed by digital home products (25–30%, includes digital television chips), tablet chips (5–10%), feature phone chips (5–10%) and Wi-Fi products (5–10%). MediaTek started shipping chips with integrated 4G LTE baseband in volume in the second half of 2014, later than its largest competitor Qualcomm. The additional cost of the separate baseband...

The Atayal Taiwanese aborigines as well as several Taiwanese Plains Aboriginal tribes (including the Taokas, Papora, Pazeh, Hoanya and Babuza people) populated the plains that make up modern Taichung. They were originally hunter gatherers who later lived by cultivating millet and taro. In the 17th century, the Papora, Babuza, Pazeh, and Hoanya established the Kingdom of Middag, occupying the western part of present-day Taichung.
In 1682, the Qing dynasty wrested control of western Taiwan from the Cheng family (Kingdom of Tungning). In 1684, Zhuluo County was established, encompassing the underdeveloped northern two-thirds of Taiwan. Modern-day Taichung traces its beginnings to a settlement named Toatun (Chinese: 大墩; pinyin: Dàdūn; Wade–Giles: Ta4-tun1; Pe̍h-ōe-jī: Toā-tun; lit. 'large mound') in 1705. To strengthen Qing control, a garrison was established in 1721 near the site of present-day Taichung Parkby Lan Ting-...
Empire of Japan
After the Qing dynasty lost the Sino-Japanese War in 1895, Taiwan was ceded to Japan by the Treaty of Shimonoseki, and the name of the city was changed to Taichū(Japanese: 臺中). The Japanese sought to develop the city to make it the first "modern" area of Taiwan and invested in roads, dams, and levees. In 1901, Taichū Chō(臺中廳)was established as one of twenty local administrative districts on the island. In 1904, the town of Taichū had a population of 6,423, and Taichū District had more than 20...
Taichung City is located in the Taichung Basin along the main western coastal plain that stretches along the west coast from northern Taiwan almost to the southern tip. The city borders Changhua County, Nantou County, Hualien County, Yilan County, Hsinchu County and Miaoli County. The Central Mountain Range lies just to the east of the city. Rolling hills run to the north leading to Miaoli County, while flat coastal plains dominate the landscape to the south leading to Changhua County and the Taiwan Straitto the west.
Taichung's population was estimated to be 2,816,667 in March 2020. There are slightly more females in the city (50.97%) than males. 24.32% of residents are children, while 16.63% are young people, 52.68% are middle-age, and 6.73% are elderly. According to Ministry of Interiorstatistics, the fertility rate in Taichung City in 2007 was 1.165 for each woman. The city surpassed Kaohsiung to become the second largest city in Taiwan in July 2017, growing at the 2nd fastest rate in Taiwan from 2012 to 2017. Recent population increases have been attributed to natural population growth, more people moving to the city, and subsidized housing.
Unlike Taipei in the north, which is solidly in the Pan-Blue political camp, and the southern cities of Kaohsiung and Tainan that are solidly Pan-Green, Taichung is more balanced, with the urban city center area leaning Blue and the suburban and rural areas leaning Green. In fact, both major political parties have won a mayoral election among the last four with at least 49 percent of the vote (Democratic Progressive Party in 1997 and 2014 and the Kuomintang in 2001 and 2005). Similarly, the K...
Taichung City's executive branch is headed by mayor Lu Shiow-yen of the Kuomintang.Taichung's legislative branch is a unicameral 46-member City Council. Each member is elected from one of six member districts where each voter has only one vote.
Taichung consists of 29 districts, 28 districtsand 1 mountain indigenous district. Inner Taichung refers to the eight former districts of Taichung City before the merger with Taichung County on December 25, 2010. Colors indicate statutory language status of Hakka language in the respective subdivisions. Note that Heping District is also an indigenous area of the Atayal people.
Taichung is home to many industries. Taichung's Industrial Zone, located in Xitun District, is home to many factories, while nearby World Trade Center Taichung hosts many industrial conventions every year. Taichung is also home to the Central Taiwan Science Park, known for the many semiconductor factories located there, most notably TSMC. Taichung is also known for its bicycle manufacturing. Notable business located in Taichung include Giant Bicycles, SRAM, and TRP Brakes. Merida Bicycles is also located in nearby Dacun, Changhua. Taichung is most famous for its suncakes. Taichung's Chun Shui Tang teahouse (春水堂) is where bubble teawas invented. The recent surge in population resulted in the growth of the retail sector,with the opening of large department stores in Xitun District.
Two railways run parallel to each other in Taichung: the Taichung Line, which passes through the urban areas in the interior, and the West Coast Line, which passes through rural areas closer to the coastal shore. Taichung railway station is located in the heart of the city in Central District and numerous bus companies provide connections to other towns by bus. The THSR Taichung Station is located in Wuriand is served both by local trains as well as free shuttle buses into the city.
Taichung Port, located on the coast in Taichung City, is the second largest cargo facility on the island capable of handling container shipping. Despite being the second largest port on the island of Taiwan, there are no passenger ferry services available and the port is closed to unauthorized personnel.
Taichung City generally follows a radial road layout, with its center at Taichung railway station. Major roads start in Central District and run outwards, including Taiwan Boulevard, Xiangshang Road, Zhongqing Road, and Zhongshan Road. Freeway 1 runs along the Fazi River on the outskirts of the city, while Freeway 3 runs along the Dadu River to the coastal plains on the west, where it then runs parallel to the coastline. Freeway 4 begins in Qingshui District and terminates in Fengyuan Distric...
Taichung City is in the process of implementing Hanyu Pinyin on road signs throughout the city. However, there are still signs displaying spellings from previously used romanization systems, as well as Tongyong Pinyin and systems that do not conform to any standard system. Unlike Taipei, which uses a capital letter at the beginning of every syllable, Taichung City uses the standard form of Hanyu Pinyin on street signs erected in recent years. However, the municipal website uses the Taipei system. Most major intersections have at least one sign containing some form of romanization. Nearly every intersection in the downtown area has signs in Hanyu Pinyin. However, outside of the downtown area, while coverage by Hanyu Pinyin signs is improving, many intersections have signs in other romanization systems (especially Wade–Giles and MPS2) or no Romanized signs at all.

Hsin-chu is the Wade-Giles romanization of the Mandarin pronunciation of the Chinese name 新竹. The same name is rendered Xīnzhú in Hanyu Pinyin and Sinjhú in Tongyong Pinyin. This name refers to the settlement's original Hokkien name Tek-chhàm (竹塹), meaning "bamboo barrier". The name may transcribe an aboriginal[which?] name meaning "Seashore". The same name is variously recorded as Teukcham, Teuxham, and Teckcham;its Mandarin pronunciation appears as Chuchien. Hsinchu is popularly nicknamed "The Windy City" for its windy climateand "The Garden City of Culture and Technology" by its tourism department.
The area around Hsinchu was inhabited by the Taokas, Saisiyat, and Atayal aborigines when the Spanish occupied northern Taiwan in the 17th century. Catholic missionaries reached the settlement of Tek-kham in 1626. The Spanish were expelled by the Dutcha few decades later.
Under the Qing, a Chinese town was established at Tek-kham by Wang Shijie and other Hansettlers in 1711. As part of the reorganization of Taiwan by Shen Baozhen, the viceroy of Liangjiang, Zhuqian Subprefecture (i.e., Tek-kham) was raised to the level of a county and renamed Xinzhu (i.e., Sin-tek or Hsinchu) in 1878. When Taiwan was made a province in 1887, Hsinchu was made a part of Taipeh Prefecture.
During the Japanese occupation following the First Sino-Japanese War, the city—known at the time as Shinchiku—was among the province's most populous. In 1904, its 16,371 residents ranked it in 7th place, behind Keelung and ahead of Changhua ("Shoka"). Shinchiku was raised to town status in 1920 and city status in 1930. At the same time, it became the seat of Shinchiku Prefecture. In 1941, its prefecture was expanded, annexing Xiangshan ("Kōzan"). Jiugang ("Kyūminato") and Liujia ("Rokka") mer...

The Hsinchu Science Parkis home to 360 high tech companies. As a result, the city has the highest income level in Taiwan. The purpose of the park is to attract high tech investment to Taiwan and to make the area the economic center for the information industry. The park is designed to cater for high quality R&D, production, work, life and also recreation. From its establishment in 1978, the government has invested over NT$30 billion on software and hardware ventures. In 2001, it developed 2.5 km2 (0.97 sq mi) of land in the park and 0.5 km2(0.19 sq mi) in southern Hsinchu, attracting 312 high-tech companies' investments. Viewing the performance of Hsinchu Science Park in the past 21 years, it can be said that it holds a decisive position in the economic development in Taiwan, with international acclaim. Although the semiconductor and related electronic businesses have been doing well, they face fierce competition from South Korea and the United States. This has resulted in lower pro...

According to early Chinese accounts, this northern coastal area was originally called Pak-kang (Chinese: 北港; Pe̍h-ōe-jī: Pak-káng). By the early 20th century, the city was known to the Western world as Kelung, as well as the variants Kiloung, Kilang and Keelung. In his 1903 general history of Taiwan, US Consul to Formosa (1898–1904) James W. Davidson related that "Kelung" was among the few well-known names, thus warranting no alternate Japanese romanization. However, the Taiwanese people have long called the city Kelang (Chinese: 雞籠; Pe̍h-ōe-jī: Ke-lâng/Koe-lâng; lit. '“rooster cage", "hencoop” or “chicken coop”'). While it has been proposed that this name was derived from the local mountain that took the shape of a rooster cage, it is more likely that the name was derived from the first inhabitants of the region, as are the names of many other Taiwanese cities. In this case, the Ketagalan people were the first inhabitants, and early Han settlers probably approximated "Ketagalan" wi...
Keelung was first inhabited by the Ketagalan, a tribe of Taiwanese aborigine. The Spanish expedition to Formosa in the early 17th century was its first contact with the West; by 1624 the Spanish had built San Salvador de Quelung, a fort in Keelung serving as an outpost of the Manila-based Spanish East Indies. The Spanish ruled it as a part of Spanish Formosa. From 1642 to 1661 and 1663–1668, Keelung was under Dutch control. The Dutch East India Company took over the Spanish Fort San Salvador...

A systematic city development started during the Japanese Era, after the 1895 Treaty of Shimonoseki, which handed all Taiwan over to Japan. A five-phase construction of Keelung Harbor was initiated, and in by 1916 trade volume had exceeded even those of Tamsui and Kaohsiung Harbors to become one of the major commercial harbors of Taiwan. Keelung was governed as Kīrun town(基隆街), Kīrun District, Taihoku Prefecture in 1920 and was upgraded to a city in 1924. The Pacific Warbroke out in 1941, and...

After the handover of Taiwan from Japan to the Republic of China in October 1945, Keelung was established as a provincial city of Taiwan Province. The Keelung City Governmentworked with the harbor bureau to rebuild the city and the harbor and in 1984, the harbor became the 7th largest container harbor in the world.
Keelung City is located in the northern part of Taiwan Island. It occupies an area of 132.76 km2 (51.26 sq mi) and is separated from its neighboring county by mountains in the east, west and south. The northern part of the city faces the ocean and is a great deep water harbor since early times. Keelung also administers the nearby Keelung Islet as well as the more distant and strategically important Pengjia Islet, Mianhua Islet and Huaping Islet.
Zhongzheng District is the seat of Keelung City which houses the Keelung City Government and Keelung City Council. The current Mayor of Keelung is Lin Yu-chang of the Democratic Progressive Party.
One of the most popular festivals in Taiwan is the mid-summer Ghost Festival. The Keelung Ghost Festival is among the oldest in Taiwan, dating back to 1851 after bitter clashes between rival clans, which claimed many lives before mediators stepped in.
