I haven't heard that shops in Beijing are going to be restricted.
Affected by e-commerce, domestic business is generally poor, and shops in Beijing are also not as good as before, especially retail. Moreover, this trend is still developing.
Now investors are very cautious about investing in shops. Store sales are also not as good as before, many businesses are constantly changing their business formats, and there are more vacant stores.
In this market situation, if someone says that shops in Beijing will restrict purchases, as a marketing manager who has lived in Beijing for more than ten years and worked in the real estate circle for more than ten years, I think it is impossible.
