During the Ming and Qing Dynasties, the feudal economy dominated the Li society, and the productivity of most Li areas was similar to that of the local Han nationality. There are many famous markets in neighboring Han areas, such as Diaonancheng, Yanglancheng, Nanfengcheng and Lingmen. The native products of Li nationality in mountainous areas flow to famous places through markets and Han merchants bought in mountainous areas, and the iron production tools and means of subsistence exchanged by Li nationality are also increasing day by day. The economic ties, cultural exchanges and intermarriage between the Li and Han peoples have promoted the integration of ethnic groups. In some developed areas in the Asian and Zhou Dynasties, the local Li people have often "traveled between cities, whether they are easy to communicate with each other or not, and sometimes they are literate." As for Wenchang, Chengmai, Huitong (now qionghai city) and other places that were developed earlier, by the middle of Qing Dynasty, the Li nationality had basically integrated into the Han nationality, and there was a saying that there was no Li in some places (such as "Wenchang has no Li"). There are also some Han Chinese who gradually assimilate into Li people, "because they are close to Li soil and are familiar with Li customs" and "benefit their landscape fields, build villages and farm fields".
In the middle and late Ming Dynasty, Miao people entered Hainan Island from Guangxi as an army. According to "Ya Zhou Zhi", "There is another kind of miaoli, hundreds. ..... Cover the Ming and Qing Dynasties, suppress Luo fire, hold two caves, build camps, and adjust the defense of Miao soldiers in Guangxi, which is called Yao archer. After abandoning the camp, the children and grandchildren are scattered in the valley, and they are still famous. " The above historical facts show that Miao soldiers were forced to settle in Hainan Island. In addition to serving as soldiers in Hainan, a considerable number of Miao people, unable to withstand class oppression and national oppression, crossed the ocean to Hainan Island to make a living.
