1 You can choose other regions, for example, I am in the United States, but you can set up a psn account in the United States, Britain and Hong Kong. Of course, you must know English to apply for lz. There is no ps3 in Chinese mainland and no service in China. You can download the demo after registration, but I suggest you choose psn in North America or Britain for your next demo. Because many games can't be tried in Hong Kong, you can't play many games with psn in Hong Kong. 3。 . . . I basically said it in 1. Can be registered globally. If you are registered in Hong Kong, you can only download games provided on Hong Kong psn, but not on American psn, so if you want to download games on servers in the United States or Japan, you just need to set up a psn account in the corresponding area. You can fill in the selected area at will in Hong Kong. I just sketched it.
