What gift is suitable for Lianyungang children to give back to their guests at the full moon?

Children in Lianyungang Ganyu always return eggs at the full moon, that is, hold eggs, which has been a custom for many years. I used to cook it myself and dye the eggshells red. Now we always stick a sticker, which can send some cooked or raw ones. If you want to return more, you can add some candy, biscuits, milk and so on.
