It is said that during the Spring and Autumn Period and the Warring States Period, there was no iron pot in the poor family, and only dignitaries could afford it! Li Shimin was seriously injured in the war with the enemy. Without medical care and food, Li Shimin became weaker and weaker, and there was nothing he could do. I met a herbalist, and I said he was a descendant of Lu. I heard that this is Li Shimin, and I love him very much. I changed it to pot-stewed pheasant and rabbit to supplement nutrition. I learned that Li Shimin was injured, so I added Chinese herbal medicine to it. After Li Shimin had eaten enough, the wound healed quickly, and then it became a prosperous time! In order to thank Lu for allowing the Lu family to use the iron pot, and their descendants hold a grand event every year to commemorate the reward of the famous monarch, and inherit this delicacy and honor, and take the secret of longevity of cast food as part of the inheritance. Pot-stewed vegetables were handed down in Lujia in this way.
