I heard that China ban sexual (or rather homosexual) content to air. I mean, it isn't because I want this to ban. But whilst there is pretty raw stuff here, they wouldn't even able to allow a kiss scene in Advance Bravely or Guardian?

 Ugly Duckling:

Idk why it's that but maaaybe (I am only guessing) it has to do something with them being a communist country. 

If that's the case, law is such a waste.  But then again,  it's not just China.  The whole world is like that, I guess: so many useless laws and the people who aren't supposed to be in prisons are in prisons while the real criminals reign the earth. 

Chinese government only just extended their homophobic censorship from mainstream TV movies social media to web series

In case you're still wondering, it's because for the production of Ambiguous focus, it was based in Taiwan, not China. The prequel to this series, I forgot the title, was produced in China, hence they got a straight couple, they did so to obtain money, and once they did, they moved the production to Taiwan and produced a more authentic film that is loyal to the original book.
