that's not young enough

it was like you were younger than "your generation", it is not vey young once one passed the age of '20'.

China is changing fast and often I found the 'over-sea chinese' lag behind mainland chinese in many area...., including concepts..., so I want to remind you that.

Growing-up is very fast so I don't agree with your "very young" concept when talk about your come-to-USA experience..

Earlier than 16 ..that can be considerred 'very young'.
