According to a report a few days ago on the website ChinaHush (reported in The New Yorker), Chinese authorities have banned movies dealing with time travel. Because they "disrespect history," which, it's been pointed out, sounds like an Onion headline making fun of a Confucian dictate more than an actual policy. But it is:
Usually the protagonist is from the modern time and for some reasons and via some means, travels through time and all the way back to the ancient China where he/she will constantly experience the “culture shock” but gradually get used to it and eventually develop a romance in that era. Though obviously the Chinese audience is fond of this genre of shows, the country’s authority… is not happy about this trend and calls a halt to the making of this type of drama.
