Where does Tangshan in Lower Nanyang mean?

The word Tangshan means ancient China!

Tangshan refers to China ruled by the Han nationality. In ancient times, all countries except the Central Plains called Huaxia people Qin people, Han people and Tang people. Now there are also sayings of Song people in some books. However, after the "five disorderly flowers" in the Song Dynasty, it was no longer a simple Huaxia nationality, but it was still different from other nationalities in the Southern Song Dynasty. During the Tang, Song, Ming and Qing Dynasties, in order to escape the war, a large number of Chinese people from the Central Plains migrated to Guangdong, Guangxi, Fujian, Taiwan Province, Zhejiang, Jiangsu, Jiangxi and other places in the south, and some migrated to Southeast Asian countries. Everyone should know about Guan Yi Du Nan, right? Overseas Chinese all claim to be Tangshan people (synonymous with China people). People in the southern coastal areas, especially Fujian and Minnan people in Taiwan Province Province, still hang doorplates at their doorways, which say where they are from, such as Wang Xing's "Taiyuan School" and "Opening Fujian to spread incense", that is to say, they are from Taiyuan, Shanxi Province, and opening Fujian to spread incense means that they are from Henan Province, and they follow the king of Fujian to govern Fujian.
