Do mainland tourists only need to apply for Hong Kong and Macao passes to travel to Hong Kong, or do they need to apply for both passports and passes?

Mainland tourists from China who want to travel to Hong Kong and Macao only need to apply for a Hong Kong and Macao Pass, and do not need a passport. You need a passport to go abroad. To go to Guangzhou to apply for a pass, you need to bring two copies of your ID card, a household registration book, photos (and the photo studio said you would know what size photos you need to apply for a Hong Kong and Macao pass) and 160 yuan to apply for a Hong Kong and Macao pass. Another important point is that you must make an appointment online, otherwise you can't apply. This is the policy of Guangzhou. But I don't know if you need it there. I looked it up on the Golden Shield before.
