The reason your limit is only one yuan is because the bank tellers have to complete the credit card task. They only apply for the card, regardless of the limit of the card you apply for.
If you want to increase the limit, you can apply for an increase in the credit limit as long as you spend 500 yuan on ICBC's credit card within a year. The limit will be higher if you reach 2,000 yuan. The premise is to save money before spending. If you are approved but do not activate it, there will be no annual fee. If the policy changes in the future, it is hard to tell. It is best to cancel it if you don't use it.
