Nowadays, the TV dramas set in ancient times are flooding the screen, and there is a relatively common scene: when the monarch holds the court, a group of ministers crawl on the ground to pay homage with three kneelings and nine knockings while shouting "Long Live! Long Live! Long Live!". Regardless of the historical background from the Spring and Autumn Period to the Qing Dynasty, as long as the monarch holds the court, there will be a bunch of ministers kowtowing while the monarch sits still high above. In fact, this is very problematic, and completely shows that it is the "hard injury" caused by directors of these historical drama for saving trouble.
