You can go to the channel in Alipay to find the official bank WeChat account you want to apply for, and then apply.
It is recommended not to apply for credit cards through any intermediary or individual (including some merchants on Taobao).
Because credit cards are related to your personal credit.
It is best to apply for a credit card in person at the bank, or at the bank counter, the bank official website, the official WeChat official account and the bank mobile app.
In China, it is completely free to apply for a credit card so far.
Don't trust those who promise that you can handle a large credit card for you. First, because they are not the auditors of the bank credit card center, they have no right to decide whether to approve the card and how much. Second, because it involves the risk of your personal information disclosure.
Don't trust people who charge by credit card.
