Historically, in the summer of 1832, a cholera did occur at the junction of Italy and southern France, and about 100,000 people died in this catastrophe.
In the process of escaping with the hero and heroine, they are surprised to find that the couple is either jumping from roof to roof, or riding horses to shuttle between ridges. In my opinion, this is not a coincidence, but an important message that the director wanted to convey to the audience: on the ground is a deadly cholera, in the sky is a man-eating crow, and people can only stand on the strange space of the roof Gou seeks to survive, all eyes see, it is a massacre between people.
At the end of the film, there is a long scene of the hero and heroine galloping on horseback on the ridge. The ridge is actually the roof of the earth in a sense, and the spatial director of this narrative never gave up until the end.
A love story about fleeing from cholera tells people: "Cholera is not scary, what is scary is the mistrust between people."
