What's the name of Degang Guo's mother?

Degang Guo's father Guo Youyuan is a retired policeman, and his mother is a retired primary school teacher, who has been living in Tianjin. It is said that Degang Guo liked Quyi when he was a child, and he was very talented in cross talk. At that time, there was a Hongqiao club in my father Guo Youyuan's film. When he goes to work, he often leaves him in the theater of this club. At that time, there were often various operas and quyi performances in the theater. He stared at what he caught, which is called hearing. To put it bluntly, it is "bathed in the milk of art" since childhood.

Guo Youyuan said: "Because I am a policeman, I know many people. One day, a friend came home and saw his children like crosstalk. He told me that he knew a good crosstalk artist named Chang Baoting, who was from Tianjin Quyi Association. Maybe he could take him to meet and learn from others one day. I didn't care, and then I forgot. I didn't expect Degang Guo to remember. A few days later, he asked me when I would take him to see the teacher. I just remembered, and then I tried to call that friend. I didn't expect him to agree at once. A few days later, someone told me that I had agreed to take Degang Guo to see the teacher. Something happened that day, but it didn't happen, or that friend took him to see it. " Later, Chang Baoting introduced Degang Guo to his first teacher Chang Baofeng.
