Zheng Zhilong was a maritime merchant and pirate who was active in the southeast coast, Taiwan Province Province and Japan in the late Ming Dynasty (his identity changed with the change of imperial policies). He is famous for his armed maritime business group and made his fortune in Hirado, Japan, where the Ming and Zheng forces originated. When Zheng Zhilong left Japan to establish a new base area in Taiwan Province Province, he not only established a powerful private navy, but also set up an official post in Taiwan Province Province, following the example of the Ming Dynasty, thus forming a separatist regime that had begun to take shape. Unable to destroy Zheng Zhilong, the Ming government turned to woo. 1628, Zheng zhilong was summoned by the Ming court, and the officials and governors knew each other. Shortly after the Qing army entered the customs, Zheng Zhilong was placed under house arrest after the Qing dynasty was cleared in 1646. The Qing Dynasty used Zheng Zhilong to subdue his son Zheng Chenggong many times, so he was imprisoned in 1655. He was killed on 166 1 year 1 1 month 24th.
Against the background of China's maritime ban in the Ming Dynasty in the17th century and the rise of the world's sea power, Zheng Zhilong established a navy division with folk power to deal with the eastern and western forces, and successfully defeated the western sea forces in the 1633 naval battle in Luoluo Bay, Jinmen Island, Quanzhou. After 200 years' withdrawal from the South China Sea, Zheng He's fleet regained the dominant position at sea, and it was a pivotal figure in East Asian waters in the era of great navigation.
