To stay in a hotel in Singapore, I need a 200 yuan Singapore dollar credit card as a deposit. What happened? What is 200 yuan SGD credit card? Where can I get it?

Generally speaking, you need to pay a deposit to stay in a hotel. When you check in at the front desk of the hotel, the front desk will swipe the prepayment right of S $200 on your credit card. Cancel it when you check out. As long as your credit card is multi-currency, you can. For example, the black multi-currency VISA credit card issued by China Merchants Bank can do this. If your credit card can only use RMB and US dollars, it should be ok. At that time, the consumption was actually buying new coins with dollars.
