Here is an example of family financial plan of a typical Chinese couple.
Husband takes care of all household bills (401K, mortgage, car, medical,
children education, vacation, etc), wife saves her salary into her own bank
accounts and spends on whatever she likes ( usually small stuff such as
clothing, jewelry , restaurants ...).
Then husband saves all the leftover into his own brokerage accounts and
spend on his hobby ( such as gun, hunting safari, ...) .
