How to get permanent platinum membership in Zhu Hua?

Platinum members of the hotel are obtained by purchasing gold cards.

1. If I live in China and buy a gold card permanently, and live with this card for 20 times in one year, I can be promoted to platinum membership. Platinum members who stay less than 20 times in 1 year will be automatically downgraded to gold members.

2. Platinum members who have stayed for less than 30 graded nights in a membership cycle, or those who have not stayed for more than 3 times, will be downgraded to the gold membership level from the beginning of the new membership cycle.
