The Dalian group buying websites I know include Tuanbao, Handan Dalian Branch, Hailu Group, Tiantian Group, Tuanle, and many others.

I feel that the difference between group buying websites is not too big, and there is generally no problem.

If you want to choose safety, it is Tuanbao Internet Cafe, where you can get a refund at any time, even after payment, which is very good. Go to Baidu to visit Tuanbao.
