"The Cat Comes to the House" is another children's literature work by teacher Ye Guangqin after "Uncle Mouse Got Up Late". The story mainly tells the story of Yaya, the mouse, who left the Summer Palace with her father and returned home to start her primary school life. The mouse Yaya who went to elementary school did not become well-behaved because she entered the school, but continued her weirdness to the end. She sang opera with her little sister in the courtyard of the hutong, and chased the tabby cat on the roof. This book will lead readers to appreciate the life in the hutongs of old Beijing through the eyes of the little girl Yaya Yaya.
