Shi Wansui was ‘valiant, good at riding and archery when he was young and fond of reading military books’ (Sui Books. Biography of Shi Wansui). After the death of his father, he inherited the title of Lord of the Taiping County.
Shi Wansui was on a par with the famous generals of He Ruobi and Han Qinhu and was promoted to the Great General of the Left Guard. He was highly talented and was reputed as “General of Cavalry” by He Ruobi. In sharp contrast with Yangsu’s severe laws and penalties, as well as killing of the innocent, Shi Wansui was hated by Yangsu for his commanding tactics and died of Yangsu’s circumvention.
