Hehe, you are so funny! Your three credit cards of ICBC share the line, with the maximum consumption amount of 1 0,000. For example, if you spend 5000 on the first card and 3000 on the second card, then the available quota of the third card is only 2000, which means that the three cards share the quota of 1 000. So it is impossible to merge into 30 thousand places. It is recommended to cancel two of them!
