What is the best group buying website in Shenzhen?

I am a loyal customer of sz555com in China, and there are many good group purchases in Shenzhen. Generally speaking, group buying in these first-and second-tier cities is ok. It's better to be practical by yourself. I am also a groupbuying fan, and the groupbuying network has saved me a lot of money. I prefer SPA to food, so I recommend it to my friends. My friends saved money, and I also earned kickbacks. Although it's not much, it's still meaningful to take it out and invite everyone to dinner, so that my popularity will be better and I will have more friends. If the landlord is also in Shenzhen, we can buy the same project and finally get together!
