Several branches of Lin Jiu came to Hainan.

The most famous in Fujian are "Jin" and "Jiumu Forest", but not all people with Lin surnames belong to these two veins.

Lin first entered Fujian in the "Yongjia Rebellion" in the Western Jin Dynasty (266-3 16). At that time, eight surnames from the Central Plains (Lin, Huang, Chen, Zheng, Zhan, Qiu, He and Hu) entered Fujian, among which Lin was the majority.

In the third year of Taining in East Jin Mingdi (325), Lu Lin footballer, a descendant of Lin Jian, was ordered to enter Fujian, where he served as the chief of Jin 'an (now Fuzhou). Later, he settled in Jin 'an County and prospered. Because all the Lin surnames who entered Fujian in the "Yongjia Rebellion" in the Western Jin Dynasty had nameless surnames, the Lin surnames in Fujian were mostly ancestors.

Then, in 669, in the second year of Emperor Taizong, more than 8,000 soldiers from Gushi, Gwangju, Henan Province, entered Zhangzhou, southern Fujian Province, including many people surnamed Lin. At the end of the Tang Dynasty, Wang San brothers, led by Wang Xu, took up more than 30,000 troops from Gushi, Gwangju, and entered Fujian, including Lin clan relatives. These two times were large-scale immigrants from the Central Plains.

Therefore, the Lins in Fujian are mainly descendants, descendants of Lins brought into Fujian by their father and son, and descendants of Lins brought into Fujian by Wang Brothers when they opened ports. Although in the whole history of Fujian immigration, the scattered people of Lin surname entered Fujian, but these people all entered Fujian in a scattered way, and their descendants have no roots to find, so these Lin surnames mostly rely on their ancestors who entered Fujian in the early stage. Their hall names and county names in Fujian are Xihe, Nan 'an, Li Wen, Xiao Zhong, Shuanggan and Jiumu respectively.
