Why are the outstanding costume dramas produced in recent years mostly Qing Palace dramas?

Judging from the current environment, the audience needs to vent their emotions and can give some inspiration to their lives. Now life is getting more and more tense, and everyone needs a relaxed emotional atmosphere. In fact, judging from the hot Qing Dynasty dramas in recent years, the dramas generally show the truth of some emotional life and bring a little sense of identity to the audience. In addition, the plot of the play paves the way for audiences of different ages to have different feelings and experiences. Therefore, when the audience has a strong response to this type of Qing drama, then the film and television drama production team will of course shoot more of this type of TV drama.
