It is found that many literati in the Song Dynasty also studied diet very well. Does the great calligrapher Huang Tingjian have any allusions? Seek the great god to popularize science

Once, Huang Tingjian invited Su Shi to a banquet to eat fish, and sent out an invitation. It didn't say "fish", but said "half Lu Hou Jiao", that is, half of the word "Lu" was prepared for you to eat. A few days later, Su Shi hosted a banquet in honor of Huang Tingjian, and the invitations were exactly the same. Huang Tingjian came to Su Shi's house, and Su Shi arranged for him to bask in the sun in the yard. Huang Tingjian was puzzled that he didn't mention eating fish. Su Shi explained: You invited me to eat the first half of Lu, and today I invited you to eat the rest. (I don't know if this counts.) Second, Huang Tingjian also wrote an article about the philosophy of diet, Five Views on Eating Time. Gu Chu, a gourmet brand in Shenzhen, was also founded by Huang's descendants in memory of their ancestors.
