Now the solar terms are suitable for ordinary people.

Cang Li knows etiquette, food and clothing know honor and disgrace. Correctly reflecting the relationship between material civilization and spiritual civilization, it is not difficult to see that "granary" and "food and clothing" are the basis of "knowing etiquette" and "knowing honor and disgrace". It is reasonable to compare material civilization to spiritual civilization, but "granary" and "food and clothing" are not necessarily "knowing etiquette" and "knowing honor and disgrace". This is one-sided, because spiritual civilization needs to be built, and the relationship between the two civilizations is unified. The construction of material civilization and spiritual civilization is dialectical, interdependent and mutually promoting. We must adhere to the principle of grasping with both hands and being hard with both hands to promote the coordinated development of the two civilizations.
