The news that China bans time-travel TV dramas and movies got a lot of attention on the internet. Yet, time travel in China is a bit different from time travel in common sense．It is anything but science fiction and always goes backwards in time．There is minimum imagination involved--no ever-ending circles that mess up present and future, no advanced technology, no new social orders or new human forms from the twenty--whatever century, everything is a known historical fact when you travel through in China．

It is not even called time travel; rather the Chinese people refer it as time crossover．Time crossover has been an extremely popular theme for online novels for years(in fact , it is an indispensible part of China’s online culture), and didn’t get picked up by TV and the big screen until recent two years．Most of time-travel dramas and movies are adapted from popular online novels and like in other cases adaptations are never better than the original books．

The main plot of time-travel novels or TV dramas can be very well summarized in one sentence: from nobody to somebody．Time travel in China is more about escaping from the reality than about realizing wild dreams．

In China , there is no need of time machine either．People travel backwards in time via the possession of antiques presence at historical places of interest encounter of life-threatening accidents or simple a look into the mirror．Some time-travel novels even start with “I wanted to go back to history so much that one morning when I opened my eyes I was back．” Technology is not relevant at all．

Though China is not short of histories to go back to, people have their own preferences and it is pretty much a gender （性别）thing．If the main character is male then he usually goes back to special times in history when he is able to help build up or tear up a dynasty．A typical example is A Step Into the Past(寻秦记), the first time-travel TV drama in China, which tells the story of how a SWAT member helps to unite China and build up Qin Dynasty ．

On the other hand , female characters primarily go back to Qing Dynasty partly because Qing Dynasty has the most number of princes to fall in love with．Yongzheng Emperor is the favorite．As can be seen in Startling by Each Step（步步惊心）, a Qing time crossover classic, a girl goes back to Qing Dynasty and falls in love with Yongzheng Emperor and his brothers．
