Why doesn't the entertainment circle sign the book?

According to Sina News, the reasons why Entertainment does not open a signing ceremony are as follows:

1. The domestic entertainment market is relatively small. Compared with overseas markets, the domestic entertainment market is relatively weak in scale and influence. Therefore, there are fewer fans of entertainment stars, and holding a signing party may not attract enough popularity and attention.

2. The publicity strategies of entertainment stars are different. Some entertainment stars may prefer to promote in other ways, such as participating in variety shows, press conferences, concerts and so on. Instead of signing a sales meeting.

3. The internal entertainment market environment is relatively complex, and some stars are affected by some factors, such as the policy environment and the rectification of the entertainment market, which makes the signing ceremony face some uncertainties and risks.
