Half-cooked melon is bitter gourd. There is a sentence in Zhang Xiaoxian's article, "When you fall in love with the taste of bitter gourd, you may not be young, at least you have been walking for half your life." In Eason's Bitter Melon, it is also mentioned that "I remember hearing people say today that this is a half-baked melon, which means that its beauty will not be insightful when it is young." When most people are young, they always hope that there can be no bitterness in life and don't like to eat bitter gourd. When they go through a certain period of life, they will know how to appreciate the beauty of bitter gourd. This "half-life" refers to the watershed of life that bid farewell to youth and frivolous learning and deep thinking, which means that by this time, all the ups and downs have been tasted, and each has its own ups and downs.
