My name is Karen.I like travelling.I have travelled to many cities in China.My favorite city is Hangzhou.It was on October lst.I went to Hangzhou to visit my friends.I felt very happy when I saw them.The weather was great.The sun was in the blue sky but it wasn't hot.The wind was really cool.After lunch,we went out and bought lots of nice things in big shops in Hangzhou.We also went to the beautiful West Lake and rowed a boat on the lake.
How exciting!We really enjoyed ourselves there.
