The Chinese General Bureau of Radio, Film and Television has prohibited new science fiction TV dramas, following a vogue for shows where modern Chinese people travel to ancient China and discover that it's not a bad place to be (this having some counter-revolutionary subtext). They've also prohibited production of "the Four Great Classical Novels", ("the four novels commonly counted by scholars to be the greatest and most influential of classical Chinese fiction"), on the grounds that the widespread adaptations of them take too many liberties with the original texts.
From the end of last year, the time-travel themed drama is becoming more and more popular. Most of these time-travel dramas are based on real historical stories but with many newly added, and usually exaggerated elements to make it funny and more attractive. Nothing is off limits in this television genre. While some find it hilarious, others think the exaggeration and even ridiculous elements added into the story is a real source of annoyance and is a disrespectful for history.
The authority's decision was made on the Television Director Committee Meeting on April 1st. - but obviously it's not a prank to fans of the drama genre. The authority has a good reason to go against the genre. "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."
