The general framework seems to be Tang era, since the capital is 长安, the central government organization is set up as 三省六部, which was established during the Tang dynasty. 六部 clearly holds significantly more political power than the other two branches (mostly appearing as departments in 六部 bullying 大理寺), which again reflect Tang era politics, since 大理寺 got more powerful in the later dynasties. The official's ranks (一品、二品 etc.) in the named positions also corresponds to Tang dynasty ranks. Further more, 金吾卫 and 京兆府 makes an appearance, and those are Tang dynasty specific departments.
However, chairs exist and the imperial exam is separated by subjects, which corresponds to the Song dynasty tech and bureaucracy. Firecrackers and fireworks also exist, which is technology that corresponds to the Song dynasty. The emperor ordered the best exam essays to get published for mass consumption, which implies the existence of the printing press, so that also corresponds to Song or later. 顺天府 gets a mention, and that department didn't get established until Ming dynasty. There's no mention yet of either 御史台 or 督察院, the former existed during Tang-Song while the latter replaced the former during Ming-Qing.
So I'd say overall, the political set up is mostly Tang with cameos of Song-Ming era departments. Technology seems pretty solidly Song. Economic development also suggests it's Song or at earliest late-Tang. Mentions of 和离书 are brought up and there seems to be no stigma associated with it, which suggests women have slightly more status, so that points more towards Tang-Song era social values. I'm leaning towards Tang era, mostly because of a lack of working women in the story; since in Song dynasty it's normal for women to start owning businesses with their own independent finances separated from men even after marriage, but the story seems to treat marrying for financial security as a norm, so that's definitely an attitude from Tang era.
Interestingly, porcelain does exist, but so far it's very much Song era porcelain descriptions (aka lacking colored patterns) and jade cups are pretty common, which again, points to pre-Ming era daily life.
So, broad strokes Tang dynasty, some Song stuff come up now and then, with the very occasional mention of a Ming-specific thing (so far 顺天府 is the only one that's obviously Ming).
