1. Physical desire is often less overworked and not excessive.

The words come from Zhang Hua's "Natural History" of Jin Dynasty. The human body needs constant exercise, but the amount of exercise cannot be excessive. Exercise is the source of good health. Proper exercise can make life full of vitality and improve one's immunity. However, excessive exercise can damage the body.

2. Rinse your mouth several times after eating to keep your teeth fragrant

The words come from Zhang Zhongjing's "Synopsis of the Golden Chamber" of the Eastern Han Dynasty. After eating, be sure to rinse your mouth several times to keep your breath fragrant. Rinse your mouth regularly to remove debris in your mouth in time and keep your mouth moist and clean, which can effectively protect your mouth and teeth.

3. Human fault also lies in mourning death, not in loving life; in regretting the past, not in cherishing the future.

From Han Xu's "Zhonglun·Revised Edition". Fault, fault, shortcoming. The shortcoming of human beings is that they only feel sad when death is imminent, but do not know how to cherish their health when they are alive; they only know how to regret the past, but do not know how to learn lessons to strive for the future. This statement shows that human nature has the weakness of regretting afterwards and not knowing how to prevent it in advance.
