What is the one in medieval European movies that turns one hand several times?

Jugongli, turning a few times with one hand, was a common etiquette in that era.

Bowing originated in China. In Shang dynasty, there was a ceremony to worship heaven, that is, to worship cows and sheep. Instead of cutting them into pieces, the whole body is bent into a circular bow, and then sacrificed in the sacrificial place to express the reverence and piety of the worshippers.

This custom has been maintained in some places until now. In real life, people gradually use this form to express their respect for people with high status or elders.

Knight baptism ceremony

According to the feudal legal tradition, chivalry can be inherited. Therefore, the son of a knight, especially the eldest son, is eligible to be a knight candidate at birth, thus forming the baptism ceremony when the son of a knight is born. Rituals are generally divided into three processes. Secular bathing. As soon as the knight's son was born, he immediately bathed the baby under the command of his father, in order to remind the knight's father of his oath as a knight candidate a long time ago.

After bathing, the baby is tied and wrapped, with his hands on his sides, his legs together and put on a gorgeous robe. Religious baptism. This kind of baptism not only makes the baby become a Christian, but more importantly, "when he is picked up from the sacred baptism tray, he not only becomes a Christian, but also becomes a Christian knight in his heart."

After the religious baptism, there will be celebrations such as singing, dancing, banquets and entertainment, and competitions will often be held for the newborn of knights. Participants often give gifts to babies.
