What are the advantages of China people in Nanyang Islands?

Since Zheng He's voyage to the Western Ocean, non-governmental maritime trade has flourished in the southeast coast of China. Residents here began to emigrate to island countries in South Asia in batches, and China culture began to infiltrate into this area, which actually created an earliest opportunity for China to develop overseas. When western colonists and businessmen came to Nanyang Islands, China immigrants had already taken root here long before them. China people have obvious advantages: they surpass Europeans in number and are closer to their motherland.
