How to express gratitude to parents with the ritual bow-down ceremony in ancient China?

In ancient China, there were four most commonly used rituals: kowtowing, nodding, empty talk and vibration.

Kutu-the heaviest person in the sacrificial ceremony, kneeling on the ground, pressing his left hand against his right hand, handing it over to the ground and staying on the ground for a period of time;

Nod-the second person will rise when he salutes and touches the ground;

Short-arch the ground with both hands, and don't lead your head to the ground with your hands;

Vibration-mourning, hitting each other with both hands, bye bye;

In ancient times, it was common to nod your head to express your gratitude to your parents-that is, when you salute, your head touches the ground. Parents are our closest relatives. They gave us life, so we should have a grateful heart to be filial to our parents. I hope you can live and work in peace and contentment in the future? Win between gestures.
