After school, Chen Haoxuan did not go out to play with Fatty and Hei Zi because his sister, Chen Meng'er, had returned. Instead, he went to the third grade with his sister to wait for his older brother, Chen Haoguo, to be dismissed.
Due to the difference in age, Chen Haoguo's third grade was a little later than Chen Meng'er's first grade.
Once Chen Haoguo's class was dismissed, someone walked out of the classroom. When he saw Chen Meng'er and Chen Haoxuan, he turned around and shouted into the classroom, "Chen Haoguo, your younger brother and sister are here to wait for you after school."
Chen Haoguo's classmates were already used to it. Every day at noon and at the end of school, there were two little kids waiting outside. Moreover, every time the first student walked out of the classroom, he would say this to Chen Haoguo.
