What does the Zhanjiang proverb: "The dog's meat rolls three times, the gods are unstable" mean?

A long time ago, there was a cook in Liuzhou who cooked dog meat very well. The local prince ate his dog meat and ordered him to deliver a dish of roasted dog meat to the palace every day. One day, the cook went to the mountain to collect spices for roasting dog meat, and accidentally broke his leg. At this time, the palace sent people to ask for dog meat.

The cook's son had no choice but to cook it for his father. After the dog meat was delivered to the government, a few seconds later a wolf-like policeman broke into the cook's house and told him that he was teasing the prince. Dog meat usually tastes delicious, but today it tastes terrible. He asked him to cook it again immediately. The cook's son didn't dare to say anything, so he had to make it again. Who would have thought that when the dog meat that you worked so hard to make arrived at the palace, it would be thrown away by the prince immediately. The prince said that he would not be able to deliver the delicious dog meat tomorrow, so he would be punished for bullying the king and his family would be exterminated. ? Disaster fell from the sky. The cook's son did not dare to disturb his dying father lying on the bed, so he hid outside the door and cried bitterly.

At this moment, a lame monk on crutches passed by. Seeing him crying, he asked him why. He told the story, and the monk said, "This is easy to handle. Ask your father to teach you how to do it. He can't do it with his hands, but he can use his mouth." He said that no matter how talented his father was, he couldn't make it without a few important ingredients. His father's leg was broken while going up the mountain to collect these ingredients. The monk laughed, took the gourd from his back, poured something randomly, and said, "Throw them into dog meat, and everything will be fine." After saying that, a gust of wind blew up, and the person disappeared.

The cook's son felt strange. When he thought about it carefully, he realized that the monk was not Tieguai Li. The next day, he had no other choice but to do as the monk said. Unexpectedly, as soon as the things given by the monk were put into the pot, they gave off a strange fragrance. After rolling a few times, the fragrance spread to the body, and my father's injury was healed. The cooked dog meat was sent to the prince's palace. The prince was so happy that he made an exception and sent a reward. The neighbors were surprised to see it. They smeared some residual soup in the pot with their fingers and tasted it. They were shocked and said, "No wonder, you are like 'dog meat rolling three times, gods can't sit still'". Immediately, the name "Fairy Dog Meat" became popular and has been spread to this day.
