Dear Li Hua,
Hello! I'm Wang Qiang.l live in Shanghai,but I'm in Hainan now. Because I'm visiting my grandma and
grandpa. Hainan is in the south of China. There are lots of beautiful places in Hainan. I swam in the sea
yesterday. I will go back to Shanghai next Sunday. You are my good friend. I hope you can come to
Shanghai someday.
Love,
Wang Qiang
