It is said that during the Qing Dynasty, Qianlong went to the south of the Yangtze River and came to a house. The owner of the house was told by Qianlong's entourage that this was Emperor Qianlong who was visiting privately incognito. He wanted to taste the special snacks of the south of the Yangtze River, so he was in trouble. Since we were a small family, braised pork was usually the richest dish at home, but what didn't Emperor Qianlong eat? I'm tired of eating braised pork. So, the hostess thought of a way to use fermented bean curd juice to cook braised bean curd pork, but there was no other way. He bravely cooked this dish for Qianlong to taste, but the result was unexpected. The emperor praised it for being delicious, fragrant but not greasy, soft and refreshing, and quickly asked about the raw materials and cooking methods. Knowing that it is made from this most common fermented bean curd juice, I can’t help but marvel at the creativity of the people.
