Are you from Guangdong? I know that there is an application from Longxing Haisi in Guangdong, and then there is a matching credit card from Longxing Haisi. This card is actually a standard IC credit card gold card, and then there are many exclusive rights. For example, if you bind Longxing Haiska to this client, you can participate in many merchants' preferential activities. Go and see for yourself. Recently, there are activities to buy oil cards. 100 yuan oil card can be bought in 80 yuan, which is still very affordable!
