Why did Zhang Zidong resign?

You can rest assured that Zhang Yiming has never left the laughing meeting room, while Zhang Zidong is very stiff, because he sent two collars and a black desk. Because Yi Ming grew up with Zhang Zidong, Yi Ming said he didn't feel well. Now Yi Ming is working behind the scenes, not recording the program. I looked at Yi Ming by the collar. You can go and have a look.
