A few small details in the travel pass (episode 9)
I was rewatching episode 9 and halfway through they show the travel pass that the magistrate issues, which acknowledges the fake province and village that "Yan Zheng" comes from.
It's a different travel pass from the one that GSY brings to the magistrate, and we know because we can see who the issuer was at the end of this travel pass, and it's signed off by the Qingping province's magistrate (ie. the one we see in the show).
Interestingly, in this piece of document they retained the original name of Lin'an (臨安) as it appeared in the novel (see blue highlight in screencap), which is different from how the town's name is shown just about everywhere else in the show (林安) - like on the gates of the town.
Another thing we know is that this travel pass was issued sometime between episode 7 and 8 because it must have been created after Gongsun Yin arrived to save the poor magistrate and his guards from Xie Zheng's wrath (LOL).
Finally and perhaps most notably, the travel pass is issued on 十六年 十二月 (ie. the twelfth month of the 16th year of the rule of Emperor Qi Sheng). This means we now know for sure that by ep8 they were still in the twelfth month (I refuse to say "December" since that's a month on the Gregorian calendar, not the Lunar calendar they used back then).
In fact, the new year only arrives partway through episode 14, since at the very end of episode 13 we see the Fans, the Zhaos, and Xie Zheng having 團年飯 (ie. family reunion dinner, which is always on the last day of the year). And then in episode 14, we see FCY and XZ wishing each other happy new year in that funny-awkward scene in the morning, and Qianqian comes to wish them happy new year too.
They really did speedrun the Lin'an arc. LMAO
