Dear Liu Fang,
Today the weather was wonderful, so I went out to the local park with some friends to fly kites. It seemed that half the city joined in us, so we had trouble find a good place to stand. But I felt so relaxing when we were done.
Over lunch, I was told that kites were invented by a man naming Mozi, who was something of a philosopher and worked hardly to bring peace between warring countries. He also created many clever inventions from wood. I think it is so wonderful that Mozi could invent something would bring relaxation and happiness to such many people. I never thought to yourself that something like kites needed a inventor.
Anyway, I have to do my homeworks. Talk to you later!
Love,
Peter
