The classical sources that credit Zhuanxu with severing the communication between heaven and earth generally specify that he did not perform the separation personally but commanded two officials, Chong and Li, to carry it out between them: Chong was ordered to take charge of Heaven and push it upward and away, while Li was set over Earth and pressed it downward, opening a fixed, permanent distance between the two realms where before, in the account preserved in texts such as the Guoyu, the Discourses of the States, gods, spirits and human beings had mingled freely, and anyone with sufficient power or knowledge could clamber between one realm and the other largely at will. This deliberate act of separation is presented in the classical commentarial tradition not as a loss but as a necessary reform: unrestricted contact between heaven and earth had allowed unauthorized figures to claim spiritual power and communicate directly with divine authority, undermining a properly ordered society, and Zhuanxu's intervention through Chong and Li is read as establishing the principle that access to the sacred should run through legitimate, appointed channels rather than being open to anyone able to make the ascent.
Some later commentators use the myth to explain and justify the existence of a specialized priestly or shamanic office, since after the separation only specially designated intermediaries, acting in effect as Chong and Li's successors, could still cross between the two now-divided worlds on behalf of the wider community, translating what had been a myth of cosmic engineering into an origin story for organized, state-sanctioned religious authority.
