Scholars in past dynasties have three explanations for "folding branches":

1, Zhao Qi, a scholar in the Eastern Han Dynasty, explained: "Fold branches, handle cases, fold hands, and untie branches." Being ashamed of being young is a service, so if you don't listen, you must not do it. According to Zhao Qi's explanation, "branches" connect "limbs", and "breaking branches" means massaging the elderly.

"Folding hands" refers to the joints that stretch the hands of the elderly; Relieve limb fatigue of the elderly by "relieving branches", "striking" and "fatigue" Young people are ashamed of this, so they are not unable, but unwilling to do such a thing.

2. Lu Yun, a scholar in the Southern Song Dynasty, and Ma Duanlin, a scholar in the Song and Yuan Dynasties, quoted Lu Yun's explanation in Yimeng Yin Jie in A General Examination of the Classics. He thought that "folding branches" meant "bending over".

Qing is a musical instrument made of jade or stone, which is hung on a shelf and makes a sound when struck. The shape of the chin is tortuous, so the word "chin closed" is used to describe the bending as tortuous as the chin when saluting, which means respect.

3. Zhu, a famous scholar in the Southern Song Dynasty, explained: "Folding branches is the elder, and folding branches and plants is the longevity of the elder. It's not hard to say

Yes "This explanation is the literal meaning of" folding branches ".

"Folding branches to be old" comes from Mencius' The History of Qi Huan. In the article, when Qi Xuanwang asked the difference between "can't" and "don't do it", Mencius replied: "I can't." Is sincere can't also; Breaking branches for the elderly, people say,'no.' Do it if you don't do it. "
