In the Eastern Jin Dynasty and the sixth year (AD 331), Nantou is the county government of Dongguan County, which governs Macau, Zhuhai, Hong Kong, Dongguan, Zhongshan, and Shantou. According to the records of the three minor yellow maps, as early as the third century BC, Lingnan had widely planted lychees. More than 1,700 years ago, Nantou was one of the political, economic, and cultural centers of the Lingnan area. At that time, there may be a large-scale lychee cultivation.
