[ Developed in speed ]
In 1851 ( the 1st. year of Xien Feng ), a business man called Lin Lan-Tien who had been living in Keelung 
harbour; aware of family safety from pirate; moved here and built three shops. That was the first shop in 
Dadaocheng. Two years later, a fighting for harbour benefit happened between immigrants in Mongga. 
Tongan immigrants were expelled by Sanyee immigrants. The losing side moved away from Mongga and 
came to Dadaocheng. They built up their own shops and harbour here.  And years later, they were lucky 
enough to take over business from Mongga where river water had already been over sanded. In 1860 ( the 
10th. year of Xien Feng ), the Second Opium War came to an end with Chinese Qing Dynasty forced to 
sign an unequal Treaty of Peiking on which the western powers dictating the terms and reaping benefits. 
However, according to the clauses, southern Anping port and northern Dan-Shui basin in Taiwan and other 
ports on Mainland China were opened to international trade. This eventually benifited Dadaocheng residents 
and boosted economy. Many foreign companies set up offices here and a number of local people became 
wealthy. Thus, Dadaocheng was ready to lead the whole Taipei city into international stage.
The major immigrants to Taiwan are from Fukien and Kuantong.  

[ The North Gate ]
The North Gate of Taipei Castle is now listed first degree cultural asset of the nation. It is located at the intersection of Zhong Xiao 
West Road and Yan Ping North Road. In 1884 ( the 10th. year of Kwang Xu ), the construction work of Taipei Castle completed when 
the Qing Dynasty was busy at war with France.  The North Gate; one of the 5 openings in the city wall; was also entitled Cheng'en 
Gate with a meaning of having the honor of being in the Emperor's favor from the north. It looked like an enclosed fort having 
important position as a main connection to Yan Ping North Road extended hrough Dadao'cheng.

[ Long time ago ]
The bicentric relation between Taiwan and Mainland China may be derived in the 3rd. century. However, there was no formal office  
ever been set on this isolated island untill 1360; or the 20th. year of Chi Cheng reign during Chinese Yuen Dynasty; when a shore 
patrol squad was set up on an islet of Taiwan named Peng'hu. During Chinese Ming Dynasty, pirates raged through the South China 
Sea. Some of those pirates chose Taiwan as their subdepot. In 1621 or the 1st. year of Tien Ki during Chinese Ming Dynasty, a pirate 
by the name of Yien Xi-Ki  with his partisans came to Chia'yee in central westren Taiwan and settled down there.

[ Outcomers ]
In 1624 ( the 4th. year of Tien Ki during Chinese Ming Dynasty), Hollander landed on the the southern coast of Taiwan near the present Tainan city and built up Fort Zelandia. Two years 
later. Spanish landed on the northern cape near the present Keelung harbour and built up Fort Sandiago. Some years later, the Spanish were expelled from the island by the Hollander. 
However, the two out-comers had stayed on this island respectively for 17 and 38 years long.

[ Ming Dynasty ]
In 1661 ( the 15th. year of Yong Li during Ming Dynasty ), Gen. Cheng Tseng-Kong commanded his troops from Hsiamen and crossed the Taiwan Straits. He succeeded to land on the
coast of Tainan and finally expelled Hollander from the island. Taiwan returned to China and government office was set up. Immigrants from mainland subdued the lands from Tainan and
extended northwards to the northern area of Chia'yee. 

[ Qing Dynasty ]
In 1683 ( the 22nd. year of Kang Xu ), Qing Dynasty defeated 
Gen. Cheng's troops and extended reigns on Taiwan. In 1709 
( the 48th. year of Kang Xu ), a mainlander by the name of 
Chen Lai-Zhang was granted to subdue Taipei area.  In 1718 
( the 57th. year of Kang Xu ), Qing government set up a troop 
at Damsui port. By then, the immigrants had settled around the 
western coast of Taiwan.  During Yong Zheng reign (1723-1735), 
population of Banchiao and Xin'chuang area neighboring Taipei 
had grown up. Some people moved across the Damsui river to 
the opposite side Mongga. Most of the people were Tongan and 
Sanyee immigrants from Chuanzhou county and some others 
from Zhangzhou county, both from Fukien provice. They worked 
hard together throughout the Kien Long (1736-1795) and Giar Qing
(1796-1821) reigns. And by the years of Dao Kwang reign, Mongga 
had already four thousands more shops and became the 3rd. biggest 
town in Taiwan as what people  called  "one Tainan, two Lokang, and 
three Mongga"
