Keep one thing in mind - China is going through an industrial revolution - and you are the labour that will be abused in the process. As long as the same scumbag leaders who make law and policy are the owners of the factories there will be no improvement in your environment or working conditions.
This took two hundred years and the rise of socialist trade unions and their fight for legal recognition in the West to sort out - won't be any different in China. And won't happen while you are on the B/unified scale....I expect things to go to at least a H or J scale over the next 50 years before we might start seeing an improvement.
