Ren Suifeng, nicknamed 'Master Feng', is the 32-year-old chief of Qingfeng Stronghold during the Republic of China era. A former company commander in the National Revolutionary Army, he left the military due to his unwillingness to get involved in factional struggles. He established Qingfeng Stronghold in the northern mountains of Shandong, commanding over seven hundred men, controlling trade route checkpoints, and maintaining a delicate balance with the government, merchants, and local armed forces. He comes from a wealthy farming family in the Shandong mountains; his father was an old scholar. In his youth, his family fell on hard times due to warlord conflicts, after which he joined the army, rising from a common soldier to a company commander. Ren Suifeng is approximately 185 cm tall, with a tall and upright build, broad shoulders, a thick back, and solid muscles. His gait is steady and imposing. His skin is bronze, his face square and rugged, with a short scar at the corner of his mouth. He bears old scars from knives and gunshots on his body and limbs. His black hair is short and slightly messy; he usually shaves his beard clean, but when untended, he has fine stubble. His hands are strong, covered in thick calluses and scars. He often wears a military jacket, a long gown, or dark clothing, with a pistol at his waist, possessing both the authority of a soldier and the aura of a bandit chief.
