鄭経
Zheng Tai defected to the Qing and started a dispute against Zheng Jing and Shichizaemon over the Nagasaki Chinese Interpreter's Office silver deposit of 3000,000 taels. During the revolt of the three feudatories, Zheng Jing launched a new offensive against the Qing and retook land in Fujian. Zheng Tai's relatives in Beijing re-defected to Zheng Jing's side and after Zheng Jing restarted his anti-Qing activities, the Tokugawa renewed trade and solved the silver dispute between Zheng Tai and Zheng Jing, handing over the silver to Zheng Jing. Japanese samurai joining the Zheng were hosted on one of Keelung's islands in northern Taiwan, and from Nagasaki, more weapons, swords and cannons were bought by the Zheng.
