The law is to help a country adjust its policies to best follow the rules. If people want to come to China, we can't simply reject them. We can't go against the pattern of international migration. For those who should be welcomed, we should offer them more opportunities, but for those who shouldn't, we must strictly control their arrival.

衡量一个国家的现代化、国际化有很多个指标。国际移民应该是其中的一个指标，因为国际流动就是人的流动, 人的流动会让整个社会活起来。它注入了新的资本、新的技术、新的思想，会激活原有的技术、资本和思想，让它们进行碰撞，产生新的东西。如果一个地区永远是本土的人，那这个地区一定是保守和落后的。

To measure the degree of a country's modernization and globalization, there are many indicators. International migration is one of them. International migration is the flow of people. The flow of people will energize a society. It injects new capital, technology and ideas into a society. It stimulates old technology, capital and ideas. When they collide, there will be new things created. If a region is only inhabited by its indigenous residents, it must be conservative and underdeveloped.
