门到门”挨家挨户的推销 is one of

the best training a kid can get. When my son was still in elementary school, we did not give up any of this chance, as we know he was shy when talking with adults. Based on my observation, many kids with chinese parents have the similar issue; of course many kids with chinese parents are known to be good at getting high scores. Nothing is wrong with getting high scores; learning to not to be shy and to express himself is just as important, if not more than, getting A.
