Can I use the discount when booking Home Inn and my Home Inn members on mobile phone WeChat?

My experience is that it is more favorable to use Home Inns membership card. Online booking should refer to business travel websites such as Ctrip or mango net. The biggest advantage of booking through them is that you can earn points and exchange gifts. However, as far as housing prices are concerned, it is definitely more favorable to apply for a membership card. The lowest price promised by the general business travel website refers to the price booked by the individual at the front desk, excluding the membership price of each hotel. I am a diamond member of Ctrip, and I also have membership cards of hotels such as Home Inn and 7 Days Chain. Home Inn and Hanting are both hotels owned by Ctrip, and they are both good business express hotels.
