I’m still not feeling 100% + the text is partial, so I didn’t translate the entirety of Pan Lihua’s travel document, but the rest is basically her titles and name, destination, and date, as far as I can see.

“Gate guard”: the previously mentioned Imperial Insignia Guard is only one of eight (each doubled into Left and Right) mostly independent Guards functioning in the capital. Imperial Insignia Guard (aka Imperial Guards here, aka jinwuwei) are probably the ones most represented in fiction for the simple reason that it’s the guard most involved in the city life, as they were responsible for patrolling the palace, the streets of the city and even the surrounding area outside the capital. The Gate Guard was responsible for conducting the checks at the gates, and technically anything apart from that is outside their jurisdiction.
