摘　　要：In physics, the symmetries and their violation always provide deep insights into the Nature. The parity (P) symmetry represents the system is unchanged under the space reflection. The violation of parity, firstly proposed by Lee and Yang and subsequently discovered in 1956, plays the key role in the understanding of the weak interaction which is one of the four basic forces of nature.
