I think it's beautiful. I'm a junior high school student, and I've read Zhang Jiajia's "There's a canteen by the cloud" and "Passing through your world". Although the author's language is not gorgeous and unpretentious, it can make people feel the same and make me relaxed. I was in the sixth grade when I read There is a Canteen by the Cloud. Cancer passed away, and Cheng Shuang passed away. A ray of light and a sentence she painted for Liu Thirteen made me feel the warmth and sensibility of the author's heart. Walking through your world is full of love, affection and friendship. I envy the author's courage of love and hate. I envy the author's sister's love for him. I envy the author very much. He can have a group of friends who help him in real life, travel with friends and have a lovely golden retriever ... Finally, I wish the writer Zhang Jiajia better and better and publish more excellent books.
