It's simple.
Cut melon in half vertically, remove seeds and slice.
Boiled water, blanched, can remove some bitterness and take it out for later use.
Oil pan, 8 layers hot, add sweet noodle sauce and stir fry. Add bitter gourd and stir fry. You can use it when you are out of the pot, and add sugar when you fry it.
Another food for reducing fire is mung bean, lily and lotus plumule.
Wash mung beans, lilies and lotus plums, pour water into the pot, boil over high heat and turn to low heat for 30 minutes.
