According to Cai Xi's survey. The validity period of the CCB card is generally displayed on the front or back of the card in the format of MM/YY (month/year). For example, 07/23 means that your card will expire in July 2023. If you are not sure whether your card has an expiration date, you can call the Credit Card Service Center of China Construction Bank (95533/400-820-0588) for manual transfer.
