What should I pay attention to when I go to Hong Kong to buy watches and go back to the mainland for customs clearance?

I am afraid of customs taxes, that is, I wear it on my hand (one). If X-rays are found, it depends on whether the customs eldest brother will check them carefully. Generally, it depends on whether the items you bring exceed the standard. If we just buy one or two watches for our own use and don't buy anything particularly expensive, it will basically not be too embarrassing for us to play. Besides, there are a large number of people going through customs. If there is no accident, it will basically be smooth and safe, hehe!
