Since the Zhou Dynasty, a complete etiquette system has been set. Today, many of these rules are not as strict as before. However, some are still followed on important occasions and are thought as examples of good manners.
Walking Etiquette
① In ancient China, while walking with someone with higher status or an old person, one should lower head, and walk a little bit behind them. If three people walk together, the elder or a teacher should be in the middle. One should bow down and walk fast using smaller steps when passing by an elder or a teacher.

Sitting Etiquette and Seating Rules
② Everyone should be sitting in a proper position at dining tables. It is based on their titles, ranks, or age. If someone doesn't know the exact position, they should wait and follow the host's lead. The best seat is the one that faces the south or the door. Hosts usually sit next to the door.

Bow and Fist-and-Palm Salute
③ Bow, known as zuoyi in Chinese, means having their hands folded in front in different ways. Today, however, the simplest zuoyi is good enough, as well as nodding, smiling, and handshaking.

④ The Fist-and-Palm Salute, is another type of zuoyi, with the right hand's fist covered by the left hand. It first appeared in the army when people holding weapons wanted to show respect for others. So, people always used the left hand to cover the right hand that held weapons.
