The father and son smiled at each other and saw that Su and his son were in the predicament of "emaciated body" and "difficult diet", but they were improvising and happy-go-lucky. Now it is.

After being demoted this time, Su Shi has made up his mind to die in the local area. The Night Travel Letter was written in the second year of the author's exile in Hainan.
