The reason why is is called ancient old skin is because it is not freshly dried peel it must be aged for at least a year before used. Towards the end the year to spring, many people will eat a lot mandarins, tangerines or satsuma. Have you ever thought of using the peel instead of chucking it into the bin. Well you can make chan pei for nothing and save you a few pennies.”
