Transfer a sum of money to the savings card at a fixed time every month and try to prove your ability. The monthly amount is relatively stable, and the higher the amount, the better. After half a year, the savings card will be used as the application materials.

Step 2 apply for a supplementary card

Family members and well-qualified relatives can apply for a credit card and a supplementary card at the same time.

3. Reasonable choice of banks and card types

The four major banks are more difficult. You can consider other banks and try some ordinary credit cards. Ordinary cards will be easier to handle than gold and platinum cards.

4. Deposit large time deposits

If you hold financial proof materials such as funds and government bonds, you can also use them to apply for extra points for your card. Choosing a bank that has business dealings with these wealth management services may also increase the card handling rate.
