Baidu Encyclopedia said that "the collision of souls comes from the collision of souls and the interweaving of souls", which refers to a noble yearning between people, a pure friendship, the interweaving of hearts and the collision of souls. It is a seamless tacit understanding, which makes the distance between each other from the ends of the earth to the ends of the earth, from a long time to an instant, from a hello to cherish each other, from letting nature take its course to the spread of mutual affinity, and its yearning vine is full of fields.
