That a single person can change history is a very dangerous idea so it’s not surprising that China is anti-time travel.

The General Bureau of Radio, Film and Television is banning all time travel stories, calling them “disrespectful to history.” translated the original story: “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.”
