This is not officially stipulated, but the local policy in various places is generally to deposit 200,000 for three months and then fill in the form and import the documents. Generally, you can deposit at least 30,000 and usually 50,000 for a platinum card. It depends on your application. If the outlets and financial managers are not helpful, they may even deposit 200,000 yuan, and then fill out a form and give a 50,000 yuan quota~
