Make the Spirit Hide Inside

The Yellow Emperor's Inner Classic (Huáng Dì Nèi Jīng) advocates that make the spirit hide inside in winter without exposing to the outside. First, calm down and think less, keep optimistic, do not bother with trifles, and do not harm the body due to the seven emotions (anger, joy, thought, sorrow, fear, fright, grief). In addition, soothing method can be adopted, to vent the accumulated and suppressed negative emotions in an appropriate way and calm the mind, so that the essence, qi, and spirit will be astringed not distracted. Anyone who breaks the rule mentioned above will damage the kidney qi, and diseases such as wei (atrophy) and reversal cold of the limbs will ensue in the next spring.
