Hello!
One of my suggestions is that do not judge one thing just by listening. Others' comments are not exactly what you think and maybe ,didn't show you the reality. Is Chinese smart or not can only be examined when you touch them,isn't it?
And, as you say literaly ,then there must be some reasons that allow Chinese goods to circulate literaly ,no matter what they are . I'm not asking for your aggrement, just personal idea.
Best wishes.
