Summarize the reasons why China people moved to Nanyang in the second half of 1960s.

Domestic social unrest, internal and external troubles, had to go to Nanyang in order to settle down.

This period of time was the most unstable period of society, such as the first and second Opium Wars and the Taiping Heavenly Kingdom Uprising, so many people chose to take refuge in Nanyang and other places.

According to research, there are many reasons why China people go to Nanyang. In the last years of China's feudal dynasty, most of them were accompanied by peasant uprisings, foreign invasions and dynasty changes, and ordinary people who could not bear the war and former nobles who lost their power emigrated overseas. Due to its geographical proximity, Southeast Asia has become the first choice for immigrants from China. Some China people go to Nanyang to change the fate of individuals or families.

According to the China Pacific Society 1935 survey, 69.95% of China people go abroad because of "economic oppression". At that time, some Chinese who went to Nanyang were full of hope for the future, while others could not stay in their hometown. At that time, Nanyang under British and Dutch colonial rule was in the process of accelerated development, and the demand for labor was very large. In order to attract Chinese workers, Nanyang countries have successively introduced a series of preferential policies.
