Hong Kong tourists buy mobile phones.

1 The mobile phone bought in Hong Kong needs to be refreshed when it goes back to the Mainland, otherwise it won't work. If you plan to buy it yourself, remember to put the machine on your body and throw away the box when you go through customs. If the machine goes through the customs in a box, it will be taxed once it is found.

You can clear customs at Huanggang Port and take a bus to Mong Kok (a round-trip ticket to 55 yuan is cheaper than a one-way ticket, and the ticket is valid for 7 days). You don't have to sign up for the tour, go by yourself. Get off at Mong Kok. There are many shops of laser and Bainaohui. I can't find anyone who asks for directions.

Don't worry about language. Salespeople can understand what mainlanders say, but it's a bit difficult. If you want to ask the way, write down the name of the way with a pen and paper, and he will naturally know what you want to do, and he may not understand what you say.
