I think there are so many ancient emperors, and the dynasties are different. There is no fixed bar, watching TV seems to have "Shang Cuisine Supervisor". Qing Dynasty about the emperor to eat, another set of terminology: is absolutely not allowed to say the wrong. Rice is not called rice and called "meal", dinner called "meal", meal called "pass meal", the kitchen called "Imperial Cuisine Room". The kitchen was called the "Imperial Catering Room". To the time of the meal - there is no fixed time, completely by the emperor's own decision - I commanded a "meal!" The small eunuchs in front of the Imperial Court will say "Pass the meal!" to the eunuchs on the hall in the Hall of Yangxin Hall. The eunuch on the temple and pass this to the bull's-eye in the heart of the eunuch outside the door, he then passed to the eunuch waiting in the West Long Street, the Imperial Catering Room eunuchs ...... so that has been passed into the Imperial Catering Room inside.
