Many publishers are vying for the book copyright of Lecture Room. All books have to be signed with CCTV, and the price is very high. When Yi Zhongtian's "Pin San Guo" was published, it even held a bid without reserve price that attracted the attention of national publishing houses. In the end, Shanghai Literature and Art Society won the publishing right of Pin San Guo with the first print of 550,000 copies and royalty of 14%.

At that time, other lecturers of Lecture Room also printed hundreds of thousands of copies, but now 20,000 copies are good. Many publishers lost money for this, and they printed too many copies in their own hands.

Weng Si, the speaker of "Lecture Room", thinks that the program has high taste, but because the emperor and the general talk too much, the topic is getting narrower and narrower. After all, the scholars in the lecture room are still those people. It is difficult for newcomers to appear, and the form has remained the same for many years. In addition, similar programs all over the country are competing to imitate. After a long time, aesthetic fatigue will inevitably occur.

Jin Bo, the host of "Cultural China", said that the popularity of "Lecture Room" in that year was the result of the joint efforts of elements such as the craze of Chinese studies, the stars of scholars and the popularization of culture. But after a long time, the novelty passed and the program did not innovate, so there was a fatigue period and a bottleneck.

Scholars who are good at speaking like Yi Zhongtian and Yu Dan are hard to find, but there are only a handful. Moreover, even if some scholars can speak it well, the academic circles do not have a high evaluation of this popular expression, and even cause controversy, which is not conducive to the promotion of academic status.
