The Chinese government has banned TV shows featuring time travel.
According to the General Bureau of Radio, Film and Television, “the time-travel drama is becoming a hot theme for TV and films. But its content and the exaggerated performance style are questionable. Many stories are totally made-up and are made to strain for an effect of novelty. The producers and writers are treating the serious history in a frivolous way, which should by no means be encouraged anymore.”
These “totally made-up” stories feature modern protagonists journeying back to a time without oppressive censorship.
