Kong Liang was the younger brother of Kong Ming. He was good-looking, had a round face and large ears, wide lips and a squarish mouth, and stood at 7 feet. Kong Liang was impatient by nature and loved getting into quarrels, thus earning him the nickname 'Lonely fiery star' (独火星). Kong Liang and his brother were both fond of martial arts so they acknowledged Song Jiang as their teacher and learned martial arts from Song.
