古人论琴，有“四德九善”之说。

Many young people like playing football very much. In China we can often see children playing football on the playground. In China and England, people call British soccer football. They don’t call it soccer.

A British soccer ball is round. There are eleven players in a team. But an American football is not round. It’s like an egg. They also have eleven players on the field in one team.
