Cao Jin was sent to his home in Degang Guo by his father when he was a teenager, and served as an apprentice under Degang Guo. The feelings of more than ten years can be said to be very deep, but in Cao Jin's heart, he always misunderstood Degang Guo and thought that Degang Guo was not good to him and was too harsh on him. So this also laid the groundwork for the outbreak of contradictions between the two of them. However, I think as an apprentice, I still have to listen to my master. In fact, many times, the master is towards you.

In the world of phonology, learning from others is still valued. Without a teacher, you can't write a family tree in the cross talk circle. For example, I didn't formally learn from my husband. Neither he nor his apprentice was recognized by the crosstalk circle at that time. Even for teachers, there are no formal ceremonies and no big banquets. Later, after studying under Mr. Hou, he and his disciples had a formal portal.

After Cao Jin left Degang Guo and Deyun Society, in order to expand his influence, he founded his own enterprise "Tingyunxuan". And enrolling a large number of students, I feel that this is not to say that I am accepting apprentices, but more like commercial cross talk. Some netizens are teasing in Weibo. Do you want to make an invoice? Generally speaking, Degang Guo took back Cao Jin's "cloud" in order to expel Cao Jin from his legacy. Now Cao Jin and Degang Guo have nothing to do with Deyun Society. Therefore, Cao Jin is equivalent to having no apprentice, and his apprentice is unreasonable. I wonder if his apprentice will be laughed at by the world in a few years.

The times are progressing, and the current cross talk circle has gradually diluted this view. Many crosstalk enthusiasts have joined in, and the crosstalk circle has gradually played down the importance of crosstalk pedigree.
