Chinese Four Seasons Health and Diet Therapy Guide

"Su Wen·The Theory of Four Qi Adjusting the Spirit" says: "In the third month of spring, this is called hair and chen, both heaven and earth are born, and all things are prosperous. They lie down at night and get up early, walk widely in the courtyard, and are slowed down to make their aspirations grow. Don't kill when you are born, give but don't take away, reward but don't punish. This is the response of spring qi, and the way to maintain health."
