2. Wash the wax gourd, dice it (the skin and seeds should be preserved), add brown sugar and mix well, and let it stand in the pot for about 15 minutes.

3. Put the wax gourd into the pot together with brown sugar water and rock sugar. When the fire boils, turn to low heat and keep it slightly boiling until the syrup becomes thick and the wax gourd becomes brown and transparent.

4. Filter the cooked juice, let it cool, put it in a clean glass bottle, seal it, and store it in the refrigerator. Dilute it with warm water or ice water when drinking, and just control the sweetness yourself.
