What does the golden waist plate mean?

Jinyaoban is the name of a bath center.

The Jinyaoban Xi'an Bathing Center, which opened in 2020, is located near the Haitian Celebrity Square in Laishan District, in the middle Binhai section of the Second Bathing Beach. It has an excellent location and the infrastructure construction is second to none among Yantai Bathing Centers. I experienced it today, and I probably won’t do it a second time.
