It was Zhu Shi. Aixinjueluo Hongli (that is, Emperor Qianlong) first entered school. Yongzheng ordered Zhu Shi to be his teacher. He set up a forum in Maoqin Hall to perform the apprenticeship ceremony. Zhu Shi's requirements for Hongli were very strict. Bian Yongzheng also felt that it was too much, so he said to Zhu Shi: "You can be a king if you teach, and you can be a king if you don't teach." This means that for the prince, educate him to be a king, and don't educate him. He is also the king, why should he be so strict? Zhu Shi replied: "If you teach him well, he will be like Yao and Shun; if you don't teach him, he will be like Jie and Zhou." This means that if you educate him well, you can make him a wise king like Yao and Shun; if you don't teach him well, he will become like Xia Jie and Shang Zhou. Such a tyrant. Seeing that what Yongzheng said was reasonable, it was hard to say anything else. After Qianlong became emperor, he was very grateful and respected his teacher. He personally went to Gao'an to greet Zhu Shi. Zhu Shi entertained the emperor with four plates and two bowls. The recipe is: Four plates of pork trotters or frozen fish with bacon, pork skin, vermicelli, and bamboo shoots, and two bowls of meatballs or potato starch balls.
