What about the membership cards of Harbin Yuanda and Song Lei?
Song Lei now spends 2,000 yuan on the day of shopping, or 3,000 yuan in a week, which is valid for one year. If it does not exceed 2000 yuan in one year, it will be invalid in the second year. If it is more than 2000 yuan. Get a new card at the service desk the next year! Yuanda Card can go directly to China Merchants Bank for a credit card, which is much more convenient.
