It still has issues: Zipcode is enough to identify the city and state, so those attributes should migrate to a city table (instead of a state table), but that data is static, so we'll leave it alone.
它还有问题：Zipcode已足够识别国家与城市，因此，这些属性应当被迁移到city表(而不是状态表)，但是该数据是静态的，因此我们可以不必理会。
There are about eight million rural children who migrate to China's cities like me and study at the nonstandard private schools because they don't have a City-Hukou.
中国现有约八百万农村儿童移居到城市后像我一样只能去不正规的私立学校学习，只因为他们没有城市户口。
If we reform the hukou system and allow people to migrate freely where they can become residents of a city naturally after a certain number of years, then the problem will naturally be solved.
如果说户籍制度的变革以后可以自由地迁徙，可以居住多少年以后就自然是这个城市的居民，自动取得户籍，那么这些问题就自然而然解决了。
