At the same time, I think he is a very smart and independent person. He knew what he wanted from an early age, otherwise he wouldn't give up his studies and cross talk with his master Yu Qian and inherit his father's business. His cleverness lies in that he will be likable from an early age, otherwise he would not give his father Degang Guo's signature to his teacher. Although when he was at school, crosstalk was not so popular now. People who like Degang Guo are not necessarily as many as they are now. His teacher happened to be among the few fans in Degang Guo.
At that time, we didn't go to school yet. Parents always send things to teachers or invite them to dinner, thinking that teachers can take care of our children at school. Even if Guo Qilin's school atmosphere was like this when he was a child, Degang Guo wouldn't do it for him. Children's minds are simple. He will give what he thinks is the best, or what he likes, to someone he respects more.
For Guo Qilin when he was a child, his father was his most admired person. The teacher who teaches him knowledge every day is the person he respects most. He gave the teacher's father's autograph only because the children liked it. Of course, this does not rule out the possibility that the teacher asked him for his signature, but I don't know whether the teacher in Guo Qilin kept Guo Qilin's signature.
