Do you know the example of the brain?

The next sentence of "phase is born of heart" is "feelings change at will", which means that phase changes with the change of mood. Basically, if a person has a smile on his face, this "smiling face" is born because he is happy in his heart, and a person looks very angry. This "angry face" is born of anger in my heart. Therefore, people who are optimistic and happy about life for a long time, people with open minds, open eyes and upturned lips, are what we call compassion. People who are proud of the spring breeze have a sense of pride, pride, happiness and self-confidence, and their faces naturally show high pride. Worried people frown, and this phase is only born of "worry", that is, the so-called heartfelt phase.
