How many nights does it take from home to platinum membership?

Home Inn Platinum Card is not available. Only when you spend a certain number of room nights in Home Inn will your card be automatically upgraded to a platinum card. Home Inn Platinum is originally a member's ordinary membership card, and then you need to stay at home frequently. When staying at the hotel, you should tell the front desk staff your membership card, which was put in the system at that time, or you can book Home Inn on Home Inn APP, and your membership number will be directly in the system, which will automatically give you points.
