At present, Du Xiaoman supports "cash withdrawal" of common bank savings cards, such as China Construction Bank, China Bank, Agricultural Bank and Industrial and Commercial Bank of China. Some local bank cards don't support cash withdrawal for the time being. I suggest you change your bank card for cash withdrawal as much as possible.
You can also log in to Xiaoman Wealth Management APP (formerly Baidu Wealth Management App)-> My-> For bank cards, click "Description of Bank Cards and Limits Supported by Xiaoman Finance" to view the list of supported bank cards.
