According to my own experience, first, it is remitted to your BOC Hong Kong account, which is handled by the Hong Kong Transit Bank (it is impossible to know which bank), and then audited by the Beijing Postal Savings Head Office, transferred to the Postal Savings Branch for review, and reached the bank card. This process will take about 3-5 working days. With the help of customer service of Qingshi Securities, gold was successfully withdrawn, and the speed was quite fast.
