The more poor the couple were, the more strong motivation they had to have their children as many as possible, which is common , or a stereotypical convince in old days in China, which, I believe, is a reasonable to develop the whole country.
However, now days , couples are much more rich than their forefathers, but more and more current young couples refuse to produce their offspring ,with their inner mind selfish, hedonism, and without their economy affording in bearing their child or children, which fact will do harm to developing whole China , and especially in future.
By the way, are there lot of grammatical mistakes in my writing above?
If only they were to correct!
Thank you.
