     I find some of the ways in which Chinese parents show love for their children rather

surprising.Obviously there are some pretty big differences between our behavior and theirs

in this respect.Most Chinese children seem to get whatever they want,from ice creams,sweets

and toys to endless attention from the adults around them.Is this a sort of spoiling or love?I

wonder.

     Most westerners would think it is a sort of spoiling rather than love.We think love means

educating your children and bringing them up to lead an independent life.That includes learning

to accept the fact that he can't get everything he wants.As an adult,he will not always get the

quite expensive car he hunts for;she will not always manage to acquire the beautiful dress

she longs for.So we try to teach our children early to cope with the disappointment of not

getting what they want.

     I find too much such kind of love for the children can actually spoil them.To my surprise,it

seems that the life of a Chinese child is rather hard.Without doubt,the child is the very center

of a whole circle of adults,but on the other hand he or she is also expected to start studying

according to adults' wishes.Many children of my son's age take piano lessons,painting classes

and even English lessons.It looks as if Chinese adults think that just playing without learning

anything is a waste of time.So in this respect our children appear spoiled,just because they

are allowed to play.But without this sort of play how can Western children develop such free

and rich imaginations?In fact the connection between this imagination and the creativity is so

important in the children' s future life.
