中國成語故事傳說：狗猛酒酸

A person of the state of Song ran a wine store. The wine was very good, and was fairly priced, and he was very kind to other people. But there was very few customers coming to his store. So later his wine became sour(酸的，發酵的). The wine store boss was so worried about this and went to consult a senior named Yang Qian. Yang told him, "The dog you keep is so fierce, people are afraid of being bitten by it. So they won't come to your store to buy your wine. This is why your wine can not be sold but become sour."

 宋國有一個酒館老板，買的酒很好，買賣做得很公平，待人也很熱情，但他店里卻幾乎沒有人光顧。 時間一長，儲存的酒都變質發酸了。老板為沒有人來買酒犯愁，就去請教鄉中長者楊倩。 楊倩告訴他說：“你養的狗很兇，人們怕被狗咬傷，都不敢來買酒，這就是酒變酸了也賣不出去的原因。”
