Symmetry and asymmetry are of great significance for our deep understanding of nature. The early study of symmetry and symmetry breaking can go back to Pierre Curie. And it was first predicted in a famous paper on the violation of the parity law in weak interactions, by Nobel prize in Physics 1957 awardees Chen Ning Yang and Tsung-Dao Lee. Since then, it has been gradually realized that symmetry breaking has a tight relationship with mathematics, physical theory, and even the philosophy of science.
