     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.
