By the way, what about Shenzhen, Guangdong and this place?

It's ok here, depending on which district it is. There are many interesting places. If you have money, you can do it. Look at the commercial street again. The electronic product is Huaqiang North, although there are many parallel imports. Shopping is at the east gate, but it's also very cheap. It depends on what grade you like, but the East Gate is really full of food.

Night market .. I don't think there is a night market in Shenzhen. If those vendors come out, Shenzhen is full of night markets.

Good hotel, Kempinski, Intercontinental Hotel ....
