During the Ming and Qing Dynasties, when Zheng Chenggong was defending Ming Dynasty against Qing Dynasty, he was named Wang Yongli of Guangxi and Wang Ping. When he led the elite soldiers to haunt the coastal areas of Zhejiang, Fujian and Guangdong, the people of Shijing Village in Nan 'an, Fujian had already entered the river from the sea, passed through Sanshui and Sihui counties in Guangdong to Huaiji, chose to live in Luoda, and gradually turned it into a village. Later, when the Zheng family was defeated, Wang Yanping and his party came to Huaiji from Fujian to escape the war and hunting, and named the village Da Lang (meaning to fight against the storm with great ambition). Shortly after Prince Yanping came to live here, other Zheng brothers who had been here found their way back to Fujian because they missed their ancestral home in Shijing Village, Nan 'an. The Zheng family who lived in Qimen village in 1999 is a descendant.
