Period of validity of Yuanzu moon cake roll in 2022

Hello, can the validity of Yuanzu moon cake rolls be extended in 2022? In 2022, the validity period of Yuanzu moon cake rolls cannot be extended. Because each mooncake coupon is marked with a face value and a valid period of use. Its face value is only used within the indicated validity period. There can be no extension. When it expires, it will be invalid, and the face value will be cleared, just like a blank sheet of paper. It's worthless. So it's best to use it up within the validity period.
