I am an Australian permanent resident with a China passport. I will go back to Huizhou, Guangdong, China, and then go to Hong Kong for a free trip. What should I do and what documents should I bring?

Hong Kong and Macao Pass. As long as you enter and leave Hong Kong from the mainland, unless you can provide an air ticket from Hong Kong to a third country (or a third country to Hong Kong) and get a seven-day visa-free stay, you can only use a pass and make a valid endorsement in other cases.

If you are a permanent resident of Guangdong province, and you have a pass before, and it has not expired. You can apply for online endorsement in www.gdcrj.com and choose express delivery service. At that time, the postal courier will come to your place to collect the certificate and send it back to you when it is finished.
