Why do you want to immigrate when you live in a third-and fourth-tier city?

Convenient for business. Since China's reform and opening up in 1980s, attracting investment has been a basic national policy of China, and the main ways to attract investment are tax reduction, exemption and preferential policies. So some people see this business opportunity, emigrate themselves or their children, and then turn themselves into foreigners, return to China to invest and enjoy various preferential policies and taxes. This friend in front of Tintin is such a person, which is also the secret of his success.
