Infinity begets Tai Chi, Tai Chi begets two instruments, two instruments begets four images, and four images begets gossip. What does gossip mean?

I ching copula: "Tai Chi is the birth of two instruments", in which Tai Chi is the state before heaven and earth opened and chaos divided into yin and yang. These two instruments are the yin and yang instruments of Tai Chi. "Biography of Cohesion" also said, "Two instruments give birth to four images, and four images give birth to gossip." . This means that all things and phenomena in the vast universe include both yin and yang, as well as inside and outside. But they are both antagonistic and interdependent, which is the general law of the material world, the procedure and origin of many things, and the fundamental reason for the emergence and destruction of things. The way of heaven and earth creates everything with yin and yang. Heaven and earth, sun and moon, thunder and lightning, wind and rain, four o'clock, before noon, and male, rigid and soft, dynamic and static, obvious convergence, everything, regardless of yin and yang. The truth of life is that yin and yang nourish hundreds of skeletons. Meridian, flesh and blood, abdomen and back, five internal organs, six internal organs, and even seven damages and eight benefits are incompatible with yin and yang. This theory has been established for two or three thousand years and is still describing Vientiane for people.
