What was the name of the person who delivered food under the ancient dignitaries?

The rise of "diners" began in the Spring and Autumn Period and the Warring States Period. "Diners" are attached to their owners and are responsible for "raising customers", with more than 3,000 people. The "diners" fortune tellers are also attached to their masters, usually relying on the families of princes and nobles, or shuttling between literati and bureaucrats to predict their future and avoid misfortune, or acting as "consultants" and "strategists". They are not only distinguished guests in the family, but also "accompany guests" on behalf of the host. They often "sit in advance" at family dinners of relatives and friends. For example, in The Record of Warriors, there was such a warlock in Li Gugu's home in Zhenyuan, Tang Dynasty. Li Gugu once hosted a banquet for Huang Bibi, Jia et al. 10, and asked him to take care of every visitor's life. After reading it, he said: the rest of the injury. According to the records in Shan Ye, there were also such "diners" in Su Yijian in the Song Dynasty. He not only calculated for the host, but also taught classes for the guests coming and going. By the Ming dynasty, the atmosphere was more prosperous. The emperor often had warlocks to follow him, making policies, marching and fighting, appointing ministers and asking them everything. Warlocks [that is, numerology] became special advisers to feudal rulers. During the period of Ming Yingzong, an important official, Shi Heng, always followed a fortune teller named Tong Yin. It was recorded in the Biography of Ji Fang in the Ming Dynasty. Needless to say, until today, we can still see such "diners" warlocks in some families. The difference is that the current fortune-telling activities are often associated with "foresight" and "qigong".
