Can the mainland go to Macau to buy a mobile phone?

Can go through customs. Chinese mainland can go to China and Macau to buy mobile phones, but it needs to pay customs duties. Electronic products are not products that can be brought into China duty-free. Once an electronic product is not a product that can be brought into the country duty-free, once it is found by spot check, no matter which port, it will be detained first, and then you will be released after paying taxes. Note that the 5000 yuan allowance does not include electronic products. Announcement No.54 of the General Administration of Customs clearly stipulates that: if an inbound resident passenger carries articles for personal use exceeding RMB 5,000, which is verified by the customs as personal use, the customs will levy taxes on the excess articles for personal use, and the undivided single articles will be fully taxed. However, the second entry and exit will no longer enjoy the tax exemption policy for articles below 5,000 yuan.
