The second grade composition tells me how to write it, 30 words.

I have a classmate named Hu Zhikang, a boy. He is chubby, with big eyes and a rosy mouth. I guess he likes gray because he often wears gray clothes.

He is a classmate who helps others. No matter who borrows something from him in the class, he lends it generously to others. Hu Zhikang always comes last in physical education class, but it seems that he has done his best. He really should lose weight. His handwriting is not very good-looking, and his homework is often not serious. He should practice his handwriting well next.

This is my classmate Hu Zhikang, the little fat brother in our class. We all like him very much.

I hope I can help you.
