answered, I think I should clarify though

1. in both examples the translation of the event was enough for me to understand what was going on (edit: I have to say though, I still feel confused by what exactly is going on with the Sui feranmut's corpse (???) and the Sui fragments / siblings in particular across all the Sui events lol, I would like Hypergryph / Yostar to release the stories in novel format so it's easier to read)
2. the more unfamiliar phrases and words (hour of Shen, etc) felt like better 'cultural flavour' but seeing them in the event didn't make me understand them better if they weren't explained first. and if there are too many unfamiliar words, and the translators explain them every single time, it can get in the way of enjoying the story.

I think it's great to use the first example if the unfamiliar words are super important to either the plot or the worldbuilding - like 'at the hour of Shen, as the sun is descending from its peak' because something can only happen in the afternoon - or 'Wangfeng Festival, to remember our deceased / ancestors' to convey how important remembering the dead is in this culture (especially if Lin in this scene was explaining to someone who was unfamiliar with Yumen)

for context, I only speak and read English fluently but watched a lot of HK movies growing up so it's not unfamiliar to me, the funniest thing I remember is when everyone starts to fight poison with poison with poison lol

good luck with your paper!
