today's topic is about "housing"

I spent lots of time to discuss discussing the topic about "housing" with my English teacher, a beautiful American lady comes from Florida, in last Wednesday's class. The view points about Real-estate in China and America are is totally different.
A young couple in China must have own an apartment or house before they get married, even if they only have 70 years usage right instead of complete proprietorship ownership. Actually, the Real-estate is so expensive that young people cannot offered buy?? it by themselves at their age. Thus, their parents, four old people, must bear the down payment which is at least 30% of total fee usually. Afterwards, the bank debt combines the fortune between finances of the parents and child more closely.
On the contrast, American young people will be more independent. They'll purchase apartments or houses by themselves, even if it'll take them a long time after they have a family. Similarly, their parents will take care of themselves without their kids's help. For example, my teacher's father and grandfather live in two states in America, and my teacher works in China.
Eventually Ultimately, it's hard to say which lifestyle is better, especially since the health system and traditional culture are totally different, but we know more about life with each other.
