The repeated phrase we heard from students justifying infringement of copyright was:
Copy and Improve.
So, as long as you improve what you snatch in China, you are not violating copyright law.
Jules has another point to make on this issue in China. Think Napster.
One of my friends once complained to me about the complexity when she downloaded some software to her her newly bought iPhone5 through iTunes. When first enter into it, she has to register a new name and have to tick all the rules that Apple Company had given to her. Sometimes, when she wants to download something, a credit card and bank account numbers are necessary and irresistible. It's true that many chinese Apple owners are bored by this problem, since they have already used got used to enjoy the endless and fruitful resources on the Internet and some certain software which can not only save time and money but also can get the achievement without their own thinking.
This behavior is viewed as a kind of cheat and desperately unrespectable to the copyright of the owner. Although it's still common in China and perhaps becoming seriously in the era, this phenomenon increasingly bring negative effect to social regulation and the enthusiastic in creativity which alarm the authority and related law departments to regulate the legislation as soon as possible.
Hence, some famous online music website like Baidu, have to change its formal free-of-charge system into a pay-as-you-download one. This reformation arouse a heatedly debate. For some of the music lovers couldn't accept that their mania had now become a burden to the cost of living and actually become a tragedy when download music. They cannot get back that sense of easiness and excitement when staring at their octet money fly away on the online-paid webpage. Apparently, the vice of the opponent outweighs the proponent which lead to this new-born law quickly nips in the bud.
We should deeply think about this deadlock. It's a tug of war between the government and the public, but if you carefully inspect this phenomenon through the veil you can easily find out that the sticking point is the contradiction of profit.
China still has a long way to go on this side. But since China is developing rapidly at a high speed, we feel confident that the consciousness of the copyright and the protection of the private property would increase gradually.
