Normally, it is once every three days. Some emperors also went to court on alternate days, which was called "inter-day court meeting."
The industrious emperor represented by Kangxi was one dynasty every day.
Morning court process:
During the morning court, ministers must get up at midnight and travel half of the capital to the Meridian Gate. At 3 o'clock in the morning, the minister arrived and waited outside the Meridian Gate.
When the drum on the Meridian Gate Tower beats, the ministers will line up; when the bell rings around 5 a.m., the palace gate will open.
All the officials entered one after another, crossed the Jinshui Bridge and formed a team in the square.
Any official who coughs, spits or walks unsteadily will be recorded by the censor responsible for picketing and will be dealt with.
Usually, when the emperor comes to the Gate of Supreme Harmony or the Hall of Supreme Harmony, all officials will kneel once and kowtow three times. Only officials of fourth rank or above have the opportunity to talk to the emperor. Ministers report government affairs to the emperor, and the emperor asks questions or gives answers.
Extended information
Everyone in the nobility knows the importance of "morning dynasty". As long as there is "morning dynasty", they can see the emperor or the princes. Above "morning dynasty", The emperor or the princes will also make very important decisions. For example, during the era of Duke Wei Xuangong of the Kingdom of Wei, two potential successors of Wei Xuangong, one was Jizi and the other was Prince Shou, were assassinated one after another in the chaos. The assistants of the two young masters, Gongzi Xie and Gongzi Zhi, "Hou Xuangong went to court early, and the two of them went straight into the court, fell to the ground, and cried loudly." It was just that they had lost their support and asked the monarch for help.
The "early court" has since become the carrier for deciding important events. When Duke Huan of Qi returns to the country and takes the throne, he must make an "early court" before he can be "congratulated by hundreds of officials." Jin Huigong also used the "Early Dynasty" to kill ten famous officials such as Pi Zheng's father and Jia Hua who wanted to welcome Chong'er. Jin Linggong also wanted Zhao Dun's life on many "morning court meetings". Many princes and kings prefer to hold ceremonial matters during the "morning court" before "giving orders". It can be said that many war decisions probably came from the "morning court".
