'Stone general' (石将军) Shi Yong was from Damingfu and made his living through gambling. He stood at 8 feet, had a pale yellowish complexion, sharp eyes and a clean shaven face.
Once, Shi Yong killed someone with a punch while gambling and fled to Chai Jin's residence to avoid arrest. Later, he went to find Song Jiang, but found out that Song Jiang was out hiding from the authorities. Shi Yong eventually met Song Jiang and delivered a letter from Song Jiang's family. In the letter, Song Qing wrote to Song Jiang, telling him that their father had died . Song Jiang wept bitterly after reading the letter and rushed home immediately, while Shi Yong followed the rest of the heroes back to Liangshan to join the band.
