I'm in Liaocheng, Shandong Province, and I want to travel to Hong Kong alone. Is it ok? How to deal with files?

You can travel to Hong Kong alone. You need to go to Liaocheng, the exit-entry administration office of the public security organ, and apply for the Hong Kong and Macao Pass in person with your ID card and household registration book. At the same time, apply for a Hong Kong visa (usually a group L visa). Because you have to take pictures, you have to go in person. The visa is valid for one year and you can stay in Hong Kong for seven days. You can go through the expedited procedures and send your visa and pass by express mail to your designated address and recipient. With the pass and visa, you need to go to Shenzhen one day in advance to find a man wearing a vest and give him 100 or so. He will declare your electronic file for you and call him the next day. He will help you with the formalities, get the form and organize a group. You can go to Hong Kong by yourself! You can come back at any pass when you come back. good luck
