During the Qing dynasty, people from Tongan county crossed Taiwan Strait and came to the north part of Taiwan.
In the seventh year of Qienlong (1742), Tongan people moved to current Dalongdong area. They built the temple “Baoankong” and their first fully planned city street called “Forty-four Kan”. During the years of Hsienfong and Tongchih, Dalongdong became the best school district in Taipei because of its great achievement in the National Exam (Kejui) and the excellent scholars.
In the third year of Hsienfong (1853), there was a violent conflict between people in Dingjiao and Hsiajiao happened in current Wanhua area. Tongan people in Hsiajiao were defeated by Sanyi people in Dingjiao, so they moved toward north to Dalongdong and Dadaocheng areas. After another two violent incidents happened in the sixth (1856) and ninth year of Hsienfong (1859), a large amount of Tongan people moved in and settled in Dadaocheng. In the tenth year of Hsienfong (1860), Danshui Port became one of the international ports in Taiwan due to the signing of Treaty of Beijing. Until then, foreigners moved into inner areas in Taipei and thus created the miracle of tea economy in Dadaocheng and made the area the business center of Taipei.
