Please translate the classical Chinese of sour wine into jokes in modern Chinese.

There was a liquor seller in Song State, who never lacked gold and beams. He is warm and considerate, and his wine is delicious, so he is famous in the local area. But the wine is sour because it can't be sold. The wine seller wanted to know why this happened, so he asked Yang Qian Yang Qian, an elder nearby, "Is your dog too fierce?" He said, "Why can't dogs sell wine?" Yang Qian said, "I'm afraid! Some people let the children take money and carry the pot to buy wine. If the dog grins and bites, the wine will be sour and can't be sold. "

There are dogs in the country, and capable people want to show their skills to the king. Ministers grin like fierce dogs, which is why talented people were not reused when they were cheated in the past.
