This novel is a work of fiction and is loosely based on the history of Song Dynasty. Any reference to historical events, real people, or real places is used fictitiously.

There are mentions of certain settings, long-standing institutions and customs, and existing ethnicities that are subject to the author's own interpretation as well as to suit the convenience of the novel. Other names, characters, places, and events are products of the author's own imagination, and any resemblance to real persons, real places, and real events is entirely coincidental. Views expressed in the narrative are not to be confused with the author's.
