1. Buy ICBC's wealth management products. Help banks complete their business, and the higher the purchase amount, the better.

2. Purchase precious metal products from Industrial and Commercial Bank of China. This is similar to a wealth management product. The purpose is to prove your financial resources. You can buy it the same day and sell it the same day.

3. Have a reasonable bank flow. This is also a common way for ICBC to upgrade its credit cards. The use method is "remote deposit and withdrawal", which can form a set of running water, so the star rating is not as fast as the first two methods.
