I'm going to live in Hong Kong soon, but I don't have any diploma. I don't know where to go and what to do. Or is there any good technology? Please help.

I have been there before. New immigrants are in an awkward position. I want to earn my own living, but I can't find a good job without a degree. I want to take Hong Kong's welfare and let Hong Kong people discriminate and call you a "locust". You should be mentally prepared and stand up to the white eyes. Although Hong Kong is a very realistic and cruel society, there are many opportunities, depending on whether you can grasp them yourself.

Generally, new immigrants from the mainland who have no skills are engaged in manual labor, such as cleaning and catering.
