Chuanbang 1: In the scene where the swallow rushed into the paddock and was shot in May, the proportion of the arrow before shooting in May was completely different from that when shooting the swallow, and it was magically shortened. (Profound mathematics, look hard by yourself)

There is a scene in the play where Wu Jinshi's imperial examination notice is posted, but the signature is written by the official department of the Qing Dynasty. Does it have anything to do with the armory office under the Ministry of War yamen?

In the third scene, Mei and Ben Mingjie fencing at the entrance of Ruyi Pavilion, both wearing masks. The time when the famous French fencing master Laboissiere invented the fencing mask should be 1776 (forty-one years after Qianlong), that is, 17 years after the start of the play, when Wei Ziyanzi was 35 years old.
