Yan Siqi (Chinese: 顏思齊; pinyin: Yán Sīqí; Pe̍h-ōe-jī: Gân Su-chê) (1586 – September 1625), courtesy name Zhenquan (振泉), was a native of Haicheng, Zhangzhou.

Because records of his early life are similar to those of the Chinese pirate Li Dan, some academics have questioned whether Yan Shiqi even existed.

[3] According to the "Taiwan Foreign Records", Yan Shiqi was born in Haicheng, Zhangzhou, Fujian, a town which had a tradition of martial arts.

Yan Shiqi escaped China on a ship and arrived in Japan, which was relatively stable during the era of Tokugawa Shogunate.

In 1624, for unknown reasons, Yan Shiqi and his brothers planned to overthrow the Tokugawa Shogunate and establish a new regime.

Among them were: Yan Shiqi, Yang Tian Sheng (deputy financial officer of Dachiban), Hong Sheng (from Putian, Xinghua), Chen De also known as Chen Zhong Ji (from Haicheng), Zhang Hong (from Hui'an, Quanzhou), nicknamed "Iron Bone Zhang Hong", who can lift 500 catties (250 kg) of bluestone, Chen Xun (from Jinjiang, Quanzhou), Lin Fu (nicknamed "Deep Mountain Monkey"), Li Ying, Zhuang Gui, Yang Jing, Lin Yi, Huang Bi, Zhang Hui, Wang Ping, Huang Zhao, Li Junchen (from Nanjing, Zhangzhou), Zheng Yiguan also known as Zheng Zhilong, father of Koxinga of the Kingdom of Tungning, He Jin, Gao Guan, Yu Zu, Fang Sheng, Xu Ma, Huang Ruilang, Tang Gong, Fu Chun, Liu Zongzhao and Zheng Yu.

Beigang had sufficient sunshine, abundant rainfall and fertile soil, it is extremely suitable for farming.

Land reclamation, required capital investment, so Yan Shiqi selected a group of people with sailing experience.

In the 16th and 17th centuries, the Dutch, Spanish and Chinese entered Taiwan in large numbers and introduced various plants, such as: mango, sweet potato, pineapple, jackfruit and so on.

In 1628, Zheng Zhilong decided to surrender to Ming Dynasty but Chen Zhong Ji refused to accept it and planned to rebel.
