Origin Story
从前，在一个村庄里住着一位老爷爷，老爷爷很喜欢种菜，而且种的菜都很美味。村民们经常去老爷爷的菜园里买菜。有一天，老爷爷的菜园里长出了一棵非常奇怪的菜，它长得又高又大，叶子也比其他的菜要大很多。村民们都很惊讶，纷纷来询问老爷爷。老爷爷笑着说：“这是我新培育的品种，叫‘巨无霸’。”村民们都很兴奋，迫不及待地想要尝尝这美味的‘巨无霸’。于是，老爷爷便将‘巨无霸’送给了村民们。村民们吃了一口，都觉得这菜的味道很怪，不像老爷爷平时种的菜那么香甜。于是，村民们便抱怨老爷爷，说他骗他们，说‘巨无霸’不好吃。老爷爷听了村民们的话，便解释说：“每个人口味不一样，‘巨无霸’的味道可能有些人不喜欢，但不能一概而论。这‘巨无霸’还是有很多优点的，比如它长得大，产量高，还能用来做很多菜。”村民们听了老爷爷的解释，才意识到自己不应该一概而论，应该具体问题具体分析。

The villagers were very surprised and asked the old man about the vegetable. The old man smiled and said: “This is a new variety that I have cultivated. It's called 'Giant Monster'.
