How about Shi Sheng Ark Travel Agency in Inner Mongolia?

It's too rubbish, the group meal doesn't make sense at all, the tableware is not cleaned, and the tour guide is terrible. All scenic spots only include big tickets, and the self-funded items are compulsory for one person 1380. I'll let you quit the group if you don't spend it. And there are not many scenic spots worth visiting. The result of going to the desert is Xiangshawan, but you only talk about it on the road or shopping almost every day until the last day.
