What were the diners before the Qin Dynasty?

The rise of "diners" began in the Spring and Autumn Period and the Warring States Period. The "guest" is attached to the master, who is responsible for "supporting the guest", and there are more than 3,000 people. The "diners" fortune tellers are also attached to a master, and usually take refuge in the homes of princes and nobles, or wander among the literati, predict their future, avoid misfortune, or act as "counselors" or "military advisers". Since the Sui and Tang Dynasties, many bureaucrats and literati have often had such warlocks. They are not only distinguished guests at home, but also "accompany guests" on behalf of the host. When gathering relatives and friends at family banquets, the host often "takes a seat in advance". For example, there was such a warlock at Li Gugu's home in Zhenyuan, Tang Dynasty. Li Gugu once hosted a banquet for Huang Pubi, Jia Zhi and others 10, and asked him to take care of the life of every visitor. He looked at it and said, "Within ten days, there will be a great disaster." Sure enough, at a banquet, the pavilion collapsed, one person died on the spot and the others were injured. According to Shan Ye's Continued Hunan, 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. In the Ming dynasty, this kind of atmosphere was even more prosperous. The emperor often has warlocks around him, making policies, marching and fighting, appointing ministers and asking them everything. Astrologers became special advisers to feudal rulers. So did the emperor, and ministers followed suit. A fortune teller named Tong Yin is always with Shi Heng, the minister of Ming Yingzong. This situation was recorded in Biography of Ji Fang in the Ming Dynasty, not to mention in unofficial history such as note novels. Until today, we can still see this kind of "diners" warlock in some families. The difference is that the current fortune-telling activities are often associated with "foreknowledge" and "Qigong".
