Why did the Guangxi earthquake explode the circle of friends of Cantonese people?

Guangdong and Guangxi in history are separated by a river. Xijiang River is a relatively large river in Lingnan, which absorbs the flowing water of Lingnan to a great extent and converges into a particularly large water system. It is definitely the mother river of Guangdong and Guangxi. The main source of Xijiang River mainly rises in Yunnan, which was originally called Nanpanjiang River, then called Hongshui River in Guangxi, and then called Qianjiang River in Liujiang. Its other tributary is called Youjiang, which began to be called Yujiang after Nanning, Jiang Xun after Guiping entered Qianjiang, Xijiang after Wuzhou entered Gui Jiang, and Zhujiang after Guangzhou.

In fact, the development of Guangdong and Guangxi turned out to be similar. There were Lingnan and East-West roads in the Tang Dynasty, and Guangnan and East-West roads in the Song Dynasty. Guangdong and Guangxi gradually began to divide and rule, and Guangzhou developed at this time. During the Yuan, Ming and Qing Dynasties, Guangxi implemented the Tusi system in minority areas, and the big and small Tusi occupied their own side and were incompatible with each other. It is forbidden for indigenous people to associate with Han people, which seriously hinders the development and progress of society. At this time, Guangdong developed rapidly with the advantage of port trade, reached its peak in the late Ming Dynasty, and slowly began to immigrate to Guangxi.

In fact, to tell the truth, in the face of the earthquake, the first reaction of Guangdong and Guangxi people is very confused. In my impression, there are very few earthquakes here. But the lack of earthquakes does not mean that Guangdong and Guangxi can get carried away. There is also the tectonic force from the earth inside the plate, which will cause the crustal rocks to fracture and form a fault zone, that is to say, the fault zone is a relatively fragile zone in the earth, where the rocks are not well connected, especially prone to displacement, deformation or fracture, and prone to earthquakes.

There are still many fault zones in Guangdong and Guangxi. The earthquake occurred this time, just above the Lianjiang fault zone in Xinyi. Xinyi and Lianjiang are both cities in Guangdong. To make an inappropriate analogy, it can also be said that the earthquake came from Guangdong. Guangdong and Guangxi are located in the relatively stable South China plate, but not in the earthquake zone.
