Hi there, thanks for reading my post.
This is based on what i've seen in Beijing， its different from what the life i have back in Malaysia.

In Beijing, although not everyone has the same lifestyle here, but you can certainly see them on the streets especially near the Central Business District in Beijing. Houses in Beijing cost around $7,000 or more per square meter, so buying mansions abroad is no problem for the wealthy class of Chinese here.

Child policy also plays a role . China's one child policy was implied for 35 years, so the wealth is carry from one generation to another. In China, the parents will take care of the child 's affairs until they get married and start a family. It 's like a tradition or a duty of a parents, meaning that a child need not be concern about not getting his first house or his first car because his parents ( usually the grandparents chip in too) to provide him so that he can get married.

This is what happens, when almost everyone in China can have only one child in the family for 3 decades.

Another fact, since land in Beijing belongs to government (leasehold), if they tear down your apartment or house for development, you will be compensated with cash or 2 more houses (some times more). This is why, Beijingers can become rich overnight. Beijingers don't even need to work anymore, their rent is good enough to cover their living expense.
