The world is just an airtight and seamless interest network, and ordinary people can't escape this trap, so they are still tied by the word interest.

Only when the truth, goodness and beauty are possessed can a complete person be considered: human nature has a desire to eat, thirst without drinking, and hunger without eating, which is of course a kind of deficiency; Whether there is a thirst for knowledge in scientific activities and a love for beauty in human nature is not lacking at first.

To see the beauty of things themselves, we must look at them from an appropriate distance.
