China Suicide Rate?

I’m looking for some data on the suicide rate in China. Ideally, the data would be stated in people per 100,000. Especially nice would be a note as to whether the total population numbers used were the official or unofficial numbers. Any reliable info would be great. I’d give bonus points if they existed for anyone who has province level data.

I have the official numbers, but don’t trust them. Is there any reason I should reconsider this bias?
