There are four seasons in one year, every season leaves me a special impression. However, autumn is perhaps the one that I like best. It usually lasts from July to September of the year. The weather is quite cool and pleasant. The sky is blue and pretty high while the sun is warm. Cool winds bring the scent of new paddy fields or guava flavor in the garden. On the two sides of the road, the colorful chrysanthemum show off its beauty in the sunshine. All the children are eagerly waiting for the school day, our parents take us to stores to buy books and other personal items preparing for new school year. Everyone is all looking forwad to seeing their friends after three months of summer vacation. Especially, in the middle of Autumn, we also breake the moon cake very happily. How wonderful is it! I hope autumn will come soon.
