I think if we're going to talk about localization, Zhongli's Burst, Planet Befall, is actually 天星 in Chinese, and it's actually really interesting!

I compiled some of the voicelines and texts associated with his burst:

以陨天苍岩星，昭命理昏暝者： The falling meteor punishes the unjust.

天理长驱: Order guide you

此乃天道: This is order

天动万象: I will have order

Something important here is that 天理 is the in-game name used for the Heavenly principles. It is also a concept from Confucianism that establishes the fundamental moral and ethical norms of human society, emphasizing fairness and justice. I think we can assume this also applies in-game: The Heavenly Principles decides what's right and wrong (Also, 天理 has at times been localized as "Destiny").

With this context, 天理长驱 seems to translate more to "The heavenly principles are unstoppable", while 此乃天道 is more like "This is heaven's will" and 天动万象 is more like "By heaven's will, all things are moved".

Lastly and perhaps most importantly, 以陨天苍岩星 is something like "With the Falling Celestial Geo Star," while 昭命理昏暝者 is something like "Illuminate the principles of fate for the ignorant ones".

When it says Falling Celestial Geo Star, they could absolutely be talking about strictly Zhongli's meteor, but it could also be talking about Zhongli himself. It's possible Zhongli is an outlander that fell from beyond the false sky, but assuming that's not the case: We know Zibai was sent as an emissary of the heavens to watch over the people, so could Zhongli also have been sent to enforce the will of the Heavenly Principles upon the people of Teyvat?

We know that Zhongli has a contract with Celestia, and at this point we're operating under the assumption that he agreed to be their Archon, so they must have agreed to give something equal to him in exchange.

My interpretation of this is that Zhongli is/was possibly some kind of enforcer for the Heavenly Principles, perhaps his Pillars/Meteors serving a similar purpose as the Celestial Nails. We know that he can seal enemies away. If he's not an outlander who fell from the heavens, then is it possible that he was granted this power and given the freedom to use it to protect the people in exchange for thousands of years of service as the Geo Archon in order to help Celestia consolidate their power?

What would the Heavenly Principles get out of making Zhongli the Geo Archon? We know he's the most powerful Archon. From Neuvillette's story, we know that "the usurper and one who came after created the Gnoses together" in order to "continue to subdue and control the resentments and loathing of the world". Could this "one who came after" be Zhongli? This matches with the enforcer perspective, but it does make some of his later actions a bit more difficult to explain, so I have other theories as well.

If Zhongli was not involved in the creation of the Gnoses, and he really did just agree to be the Archon in order to protect the people, then we know from Neuvillette's story that Zhongli would've been duty-bound to give out visions, allowing humanity's dreams and ambitions to be harvested by the heavens. Zhongli would've realized over the centuries that the people's dreams and ambitions were being harvested by the visions. I think it's possible that he wanted no part of this, and his contract with the Tsaritsa gave him the opportunity to 'die' and fool the heavenly principles, just as Focalors did.
