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.
        甜檸檬一詞來源于一句俗語：“生活給你檸檬，就榨檸檬汁吧。”意思是在最壞的情況下盡力做到最好，就算要往檸檬汁里倒進許多糖直到它味道變甜。甜檸檬的反義詞就是酸葡萄（吃不到葡萄就說葡萄酸）。

        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，當人們追求目標失敗時，他們可能會試圖美化結果，以讓自己內心感到安寧。這就叫“甜檸檬心理”。
