"The destruction of Shuangyu disrupted the relatively orderly system of illegal trade previously centered around the port, and the smugglers scattered across the Chinese coast, with some becoming pirates in the process. For his part, Wang Zhi re-established himself at Ligang and continued expanding his consortium. He adopted Mao Haifeng, a Zhejiang trader skilled in the use of Portuguese cannons, as his son and utilized the latter's knowledge to fit his ships with cannons. In 1551, he led a coalition of merchant-pirates to destroy his rival Chen Sipan with the connivance of the Ningbo military officials. With Chen Sipan defeated, Wang Zhi's supremacy in the China seas was assured. Many pirates fell in behind Wang Zhi, and it was said that no ship dared to sail without his banner."
-The destruction of Shuangyu looks like Great Age of Pirates but he is a member of Rocks Pirates, so maybe he started piracy again after the Great Age of Pirates began and created his own consortium?
