Why must always suggest put up signs, notices, or warnings.
The cause of this is lack of education, from childhood, a
generation ago.
How can parents teach their children civility, if they
themselves lack it.
you are spot on. low or no education the previous generations.
how can they teach their children manners, when they were not
taught by their parents basic manners. its a vicious cycle really.
plus chinese people are now known for their manners, even for
highly educated and well brought up people.
