In the middle and late Tang Dynasty, Fulao people began to migrate to western Guangdong. At the end of the sinicization of Li nationality in Maoming, it also occupied a large number of contiguous areas and settled on a large scale, forming regional residents independent of Guangfu people. This is the situation of Fulao dialect island in Dianbai County. What they say is Li (slang, thunder) dialect, which is actually a fusion of Fujian immigrants, slang descendants and Guangfu people. Li dialect belongs to Minnan language family, but it is very different from Minnan language.

In Gaozhou, Guangfu clan is dominant, and Fulao clan can only enter through infiltration, and most of the descendants of these Fulao clans no longer speak Minnan.

South Gate of Gaozhou, West Gate of Gaozhou, Shigu Ruins, Dahan Village of Surabaya, Jiebaopo Village, etc. There is a Tianhou Temple or a shrine to the goddess of heaven, also known as Mazu and Tian Fei. Gaozhou people also call it Aunt, which originated in Zhangzhou, Fujian, and may be brought by Fujian commercial immigrants. Gaozhou puppet show was also introduced from southern Fujian in the Ming Dynasty. It can be seen that Minnan culture has a great influence on Gaozhou culture.

The most popular surnames of the so-called Gaozhou Fujian immigrants are Lin, Cui, Cai, Chen, Xu, Zheng, Ke and Zou. Of course, not all of them can be confirmed.
