Yang Lin is a fictional character in Water Margin, one of the Four Great Classical Novels in Chinese literature. Nicknamed "Multicoloured Leopard", he ranks 51st among the 108 Heroes and 15th among the 72 Earthly Fiends.
Background
Originally from Zhangde Prefecture (; present-day Anyang, Henan), Yang Lin is described in the novel as a man with a round head, large and beautiful eyes, a straight nose, a squarish mouth, a narrow waist, and broad shoulders. A highly-skilled fighter who specialises in using an iron spear, he is nicknamed "Multicoloured Leopard".
Meeting Dai Zong
Yang Lin is first introduced in the novel as a wandering outlaw. By chance, he encounters Dai Zong, an outlaw from Liangshan Marsh, who has been sent to Jizhou (; present-day Jizhou, Tianjin) to fetch Gongsun Sheng. Although he has never met Dai Zong before, he deduces Dai's identity from his speedy pace, and calls out to Dai by his nickname, "Magic Traveller". Dai Zong, surprised that a stranger recognises him, stops and greets him. After Yang Lin introduces himself, Dai Zong invites him to join the outlaw band at Liangshan Marsh and takes him along to find Gongsun Sheng.
Along the way, Yang Lin and Dai Zong pass by Yinma River (; in present-day Jizhou, Tianjin) and encounter an outlaw band led by Pei Xuan, Deng Fei and Meng Kang. It turns out that Yang Lin and Deng Fei are old acquaintances. At Dai Zong's invitation, the Yinma River outlaws also join the Liangshan outlaw band.
Battle against the Zhu Family Village
Yang Lin appears again in the novel when the Liangshan outlaws are attacking the Zhu Family Village, a fortified village run by the three Zhu brothers and their father, who are hostile towards the outlaws.
Yang Lin, volunteering to scout the terrain and gather intelligence, disguises himself as a Taoist priest and infiltrates the village. However, he is discovered by the enemy and taken captive. He is freed only after the outlaws defeat the Zhus and overrun the village.
Campaigns
Yang Lin is appointed as a Tiger Cub Patrol Commander of the Liangshan's cavalry after the 108 Heroes are fully assembled. He participates in the campaigns against the Liao invaders and rebel forces in Song territory after the outlaws receive amnesty from Emperor Huizong.
During the campaign against Fang La's rebel forces, Yang Lin joins Mu Hong in successfully carrying out an espionage mission in Runzhou (; present-day Runzhou District, Zhenjiang, Jiangsu). After the Liangshan forces capture Hangzhou, Yang Lin falls sick and has to remain in the city to recuperate, hence he is not involved in the final battle.
Yang Lin is one of the few Liangshan heroes who survive all the campaigns. Although the emperor offers him an official appointment to honour him for his contributions during the campaigns, he declines and chooses to return to Yinma River with Pei Xuan to lead a peaceful life.
