Why did the people of Nanxiong Zhuji Ancient Alley move south?

The history of the southward migration of Zhuji Lane people is divided into two parts. The first part is that a large number of Central Plains people moved to Lingnan to avoid the war and settled in Zhuji Lane. The latter part are descendants of the Central Plains who thrived and lived here [for the same reason, they moved to the Pearl River Delta further south, and then dispersed from the Pearl River Delta to Southeast Asia]. After moving in and out for thousands of years, the ancestors' roots spread like a net, taking root as far away as overseas, forming today's root system with lush leaves all over the world.
