The fact that 2 19 people are forbidden to buy duty-free goods outside Hainan Island within three years must be that these 2 19 people made some mistakes when buying duty-free goods outside Hainan Island for some special reasons, so Hainan prohibited them from buying these duty-free goods outside Hainan Island. In this regard, they should also review their own series of behaviors, whether there are some flaws in their daily normal operation, which makes them make some mistakes in purchasing duty-free goods in Hainan Island, which leads to their being forbidden to buy these goods. These goods are probably necessary for them, but they can buy them in other ways. They don't need to go to Hainan to buy in person, but they can also complete their daily needs through a series of purchasing by others. Therefore, these 2 19 people should seriously reflect on whether their behavior is goodwill when buying goods, or whether they are prohibited from buying because of some illegal acts. The punishment for them is certainly very suitable for them, and the relevant government should also have some evidence to make a series of judgments, so it is natural to say so.
The above is my opinion that it is forbidden to buy duty-free goods in Hainan Island within 2 19 three years.
