Yan Qing was from Damingfu, Beijing. He lost his parents at a young age and was brought up by Lu Junyi, who allowed Yan to work as a steward in his home. Yan Qing was extremely loyal to Lu Junyi and was Lu's right-hand man.
Yan Qing stood at about 6 feet, had a handsome face, red lips and thick eyebrows, with broad shoulders and a narrow waist. His torso was covered with flowery tattoos as a gift from Lu Junyi who took him to see a master tattooist. And because of his pale complexion, the tattoos stood out with magnificent beauty. Yan Qing was also a skilled dresser, dressing both well and on occasion, often aiming to show off his flowery tattoos. Apart from his martial arts, Yan Qing was also an accomplished musician. There was no instrument that he could not play, nor was there no song he could sing. He was a splendid actor who did well to often disguise himself into the roles of others to infiltrate deep into the capital city.
