Long-term use of credit cards and timely repayment are of course important, but banks are also important. For example, the card of the Agricultural Bank of China spent 10,000 yuan four years later. No matter how you apply, you won't be promoted. And my CCB card is 5000 yuan, and now it is 60000 yuan. So banks are also very important. If it belongs to CCB, I suggest you use it more in other places, but don't always use it on one machine, and don't always use it in full, which is suspected of cashing out. Especially in tertiary hospitals, the number of places has risen rapidly.
