Why didn't Liang Hongda host the Avenue of Stars?

In fact, it seems to me that the Avenue of Stars should want this person to be the host, but the other party is not very happy, because why should they participate in other people's programs when they have their own programs? After all, our own programs are all produced and developed by ourselves. We just want to be a program or simply be a host, and we don't want to waste time.
