In Chinese history, the Song Dynasty has always been known as a "weak military". Perhaps it was the fate of the country that led to the emergence of many generals during the era when the Song Dynasty emphasized culture over military affairs, allowing the precarious Song Dynasty to continue for more than 300 years.
Liu Fa was a man who could be called a "divine general" in unofficial history. The King of Xixia even praised "many generals, with Fa as the leader."
The author compiled the life of General Liu Fa based on many county chronicles and unofficial histories. The book contains many personal guesses and jokes.
