The term sweet lemon comes from the saying, "When life hands you lemons, make lemonade." It means making the best of a bad situation, even if it involves mixing lemons with cuploads of sugar until they actually taste sweet. It is the equal opposite of sour grapes.

甜柠檬一词来源于一句俗语：“生活给你柠檬，就榨柠檬汁吧。”意思是在最坏的情况下尽力做到最好，就算要往柠檬汁里倒进许多糖直到它味道变甜。甜柠檬的反义词就是酸葡萄（吃不到葡萄就说葡萄酸）。

In daily life, when people fail to achieve some goal, they may try to sugarcoat the result, in order to feel peaceful. This is called “sweet lemon psychology”.

在日常生活中，当人们追求目标失败时，他们可能会试图美化结果，以让自己内心感到安宁。这就叫“甜柠檬心理”。
