I come from Liuzhou, Guangxi, and work in Guangzhou. What should I do if I want to travel to Hong Kong and Macao?

You can't find anyone else to do it for you. You must bring your ID card and household registration book to the public security bureau where your household registration is located to apply for the Hong Kong and Macao Pass. You also need to take a special Hong Kong and Macao pass with a blue background. Go to the photo studio and say that I will take a Hong Kong and Macao pass and they will know. You'd better take a photo with you when you go to apply for a certificate, because that photo should be very strict. If you fail, you have to shoot again, show your forehead and wear dark clothes with a collar, so you should wear good clothes when taking pictures. Then just bring your ID card, household registration book and photos. Go to the public security bureau and tell them to apply for Hong Kong and Macao passes, and they will tell you what to do.
