According to the membership grade of Sanfu Mall official website, Sanfu membership cards are ordinary cards, silver cards, gold cards and platinum cards from low to high, which will be upgraded step by step according to the user's consumption quota and will not be downgraded. Sanfu Silver Card requires a higher consumption quota than ordinary cards. Once you become a member of the silver card, you will not return it to the ordinary card because of the low consumption quota. The membership mechanism of Sanfu Mall encourages users to increase their spending amount to improve their membership level. Therefore, it can be confirmed that Sanfu Silver Card will not be downgraded to an ordinary card, and its membership can be retained. This is in line with the higher entry threshold and preferential policies of silver cards. To sum up, Sanfu Silver Card will not become an ordinary card.
