I come from the north. I want to go to Hong Kong to find a job in IT. Go to Hong Kong to find a job. What should I pay attention to? Hong Kong and Macao Pass, I know this.

First of all, you can't find a job with a Hong Kong and Macao Pass, and employers can't hire such people (illegal). You must first find a Hong Kong company that can help you apply for a work visa. Only after he is willing to invite you and apply for it for you can you go. Another way is to apply for a work visa on the Internet of the Hong Kong government, and then find a job. But the success rate of this method is very low, unless you are Lang Lang or Liu Xiang.
