What does the membership card of Home Inn mean?

This is the membership card of Home Inn. Home Inn members are divided into home inn members and home inn gold medal members.

Guest members enjoy a 9.2% discount on the room rate.

Guest gold members enjoy a 28% discount on the room rate.

You can fill in the membership registration form at the front desk of the hotel. If you buy a guest card in 40 yuan, you can upgrade to a gold card with a score of 2000. Or register online. Now it's half price, and 20 yuan can become a member.

This is the previous information. I wonder if it has been changed now.
