Is Beijing Sun Palace Kaku Technology Water Park dirty? (There must be a reason, real)

The ground is covered with mud and it is not clean. The service is not good. It is said outside that there is no cash transaction in the park. You need to apply for a card and rent a locker inside. You still have to pay to go in and have to rummage through the bag. They are not allowed to bring water. It is really bad. Yes, I went there yesterday. It's quite small. Usually adults take their children to play there. Adults can also play, but it's too small and it's boring to shoot ads. It feels pretty good. In fact, it's too bad. The water in the pool is cold and very wet. There are some dark things in the dirt
