My hukou is in Shenyang. What are the procedures for traveling to Hong Kong?

To go back to Shenyang to apply for the Hong Kong and Macao Pass

You need to go through the relevant formalities at the Exit-Entry Administration Center where your account is located. Because Shenyang is an open city of Hong Kong and Macao, you only need to bring your ID card account book, and you can bring your own two-inch photo or take it at the Exit-Entry Administration Hall, and you can pay the fee. You can fill out the application form for the Hong Kong and Macao Pass at the Administration Hall, and it will usually be processed within 15 working days except for the bigger cities such as Beijing and Shanghai.

I hope I can help you.
