Going too far is as bad as not going far enough.
Explanation: excessive; Jude: Yes, yes; Less than: out of reach. Doing too much is just like not doing it, which is inappropriate.
Zi Gong, a student of Confucius, asked Confucius who was smarter, his classmate Zhang Zi or Xia Zi. Confucius said that Zhang Zi often exceeded Zhou Li's requirements, while Xia Zi often failed to meet Zhou Li's requirements. Zi Gong asked Zhang Zichao if it was better. Confucius replied that the effect of exceeding and failing is the same.
Therefore, the "harmony" of "harmony is precious" is not "harmony", and the emphasis is just right, which is almost the same as going too far.
