The Longka Car Card provides a weekly discounted car wash service. When the retail price of the car wash service is equal to or lower than 15 yuan, the cardholder can enjoy the car wash service without paying a fee; when the retail price of the car wash service exceeds 15 yuan, the excess amount will be used by the cardholder to use car card points (the exchange ratio is 4 ‰, that is, every 1,000 points is converted into RMB 4) for payment. When the balance of points is insufficient, payment is made in cash. You can check the specific car wash locations on the CCB official website.
