Shanghai seems to be a large number of immigrants from the Central Plains, and there are few Baiyue locals. Why?

It's too far. There are many mountains to climb and many Yangtze rivers to cross. Besides, Shanghai was only a small fishing village a long time ago, and it was not as prosperous as Xi 'an and Jianye. Baiyue people will choose local immigrants from the Central Plains first, and then immigrate from the Central Plains to Jiangdong. It is also a person after several generations of Baiyue, and Baiyue's lineage has long been weak. Nowadays, only those who still live in Baiyue have pure Baiyue bloodline.
