Why doesn't redemption on the blade play?

The reason why "Redemption on the Blade" failed to air may be because it failed to pass the examination and approval. The examination and approval of TV plays is a law formulated to standardize the management of TV plays, prosper the creation of TV plays and promote the healthy development of TV play industry. Specifically, it may be because the content or theme of the TV series does not conform to the relevant provisions of the state, or it may be because the technology or production problems failed to pass the review. The specific situation may require relevant official announcements or news for more details.
