My personal experience is very good. I went shopping in Xizhimen with my friends last Wednesday. I happened to be hungry and wanted to eat something, so I searched with Kahui, and there happened to be a Jinhans event in Xizhimen. , use a China Merchants Bank card, if two people travel together, one person will be free of charge. There were exactly two of us, so we only spent the price of one person, which was very worth it! If it weren't for Kahui, it would be difficult to find discount information in the surrounding area, so I love Kahui very much.
