As I see my colleagues in China; they are mostly wasting time to stay the longest in the office. I know a few guys who have some shares, that either do not go home or go home for 3-4 hours only. They arrive at 6 am, leave at 8 pm and then go to KTV to do sales which basically means drink like a maniac. And then either back to the office or home for a quick nap. Their boss does not directly tell them to but he does go crazy when they underdeliver or deliver past deadlines, so they show they did anything. Not sure if it helps or not. Some of them seem happy and content doing that life and show no signs os stress even at 40y/o, some are walking dead. The happy ones seem to be the ones that are well paid and get to sit and write code, while the unhappy ones deal with red tape and meetings. Which is what usually happens in my experience in the west as well.
