I also have 150,000RMB income in China, and after come to Canada, most of people can't find a job. even if they have one, your money left is only 10,000CDN, I guess. And much much more stress here. You don't know when you will lose your job. Dont' come.
I have job now, very busy, few income, high pressure in work, tooo bad, and the money in my pocket is too samll....
