Dear Lucy,
How is everything going? You asked me about my favourite season.

      My favourite season in Nanjing is autumn. The weather is cool and sunny, not too hot or cold. You can see many beautiful red and yellow leaves on the trees in parks like Xuanwu Lake Park. People often fly kites or have picnics there. My favourite activity is going hiking with my family in the Purple Mountain. It's so relaxing to enjoy the fresh air and beautiful scenery. I hope you can come to Nanjing in autumn. I will show you around and we can have a great time together.
