The practice of greedy frog originated from the ancestral cookbook of a big squire named Liu in Yubei. According to his descendants, there is a story about how his family got the secret recipe of this dish: during the Qianlong period of the Qing Dynasty, Liu was the largest family in the area, and Mr. Liu was charitable and had high prestige. The old man has only one hobby in his life, that is, collecting folk recipes. On the one hand, he can compile them into a whole book and pass it on to future generations, on the other hand, he can have a good meal. One day this winter, it suddenly snowed heavily in the sky, which lasted for a day and a night. The old man was exercising in the yard when he got up, when he suddenly heard the janitor's family shouting, "An old flower froze to death at the door." The old man came to the gate and saw an old flower lying on the stone steps, ragged and unkempt, covered with a thick layer of snow. The old man frowned and sighed, "Hey! Find a good place to bury it! " At this time, a family member replied: "Sir, this old flower seems to have a breath." The old man was very happy to hear this, so he quickly ordered the servant to carry the old flower into the house for treatment and send someone to take care of it. Three days have passed, and presbyopia can already walk around. He told the housekeeper that he wanted to see the old man and thank him. The housekeeper said angrily, "The old man is bored, so how can he have time to see you?" It turns out that in recent months, the old man has not got the recipes worth collecting, and he is unhappy every day.

Old Huazi laughed and said to the housekeeper, "My old Huazi has been wandering in the Jianghu for decades and learned a dish, which will definitely make the old people laugh one by one and repay him for saving his life." Old Hanako asked the housekeeper to prepare all kinds of necessary items for him. Cooking alone behind closed doors. Soon, a spicy aroma floated out of the room, which attracted the old man who had lost his appetite for several days. It turns out that this dish originated from beggars begging for food, catching wild frogs at the edge of the field to satisfy their hunger, and Lao Huazi integrated his taste knowledge of eating hundreds of meals for decades before he got this delicious food. Finally, the old flower gave this dish to Mr. Liu, which has been passed down to this day.
