You are learning "Chinese" - good. After you learned it, you should talk to Chinese people to hear what they think about your ideas. Porn is not legal in China, you say. Some Chinese people might be doing porn illegally. Make contacts. Yes... Increase the number of people you know. Of course, represent mainstream enterprises. Take a look at foreign currency as something to be exchanged to use in any country. Change Yuans into Dollars, for example. Anyway, China censors internet. Hmm... It's just not a completely globalized economy. To keep our sanity, we literally have to think of countries as separate entities. Good luck.

You can do well there. Learn the language and treat your business like a business.

Not sure about getting into adult there, though... :(

Whoa, let me stop you there.

Learning a language is not like making a cup of tea, yo.

I've been there for a month, and loved it also. Chine is not what people think it is, but this is good. When the majority of the people discovers China is better than they think, we are already in there having profit ;)
