Some gourds are indeed very bitter, and bitter gourds should not be eaten. In rural areas, pigs are fed bitter gourds, and even the pigs don't eat them. This shows that bitter gourds are extremely bitter. When buying a gourd, you should first tell the vegetable farmer whether it can be tasted. If it tastes good, buy it. If it doesn't taste good, don't buy it. When you taste the gourd, bite off a small piece near the handle (root) of the gourd. Taste whether it is bitter or sweet. As long as it is not bitter, buy it. Because there was a covenant beforehand, the suffering is still his.
