Is it cheap to book a hotel on Meituan or Ctrip?

Meituan is cheaper, and some hotels will have activities, such as booking rooms at half price after 8 pm. What can Ctrip say? It is very cheap when there are activities, and you will get a refund when you stay, but now such activities seem to be rare. If it is not for special circumstances, it will be cheaper, but it will not be much cheaper.
