Cheng Yin 程銀

In Chapter 58 of the Romance, just as Ma Chao has raised the troops of Xiliang and is about to set out, Han Sui, Administrator of Xiliang, summons Ma Chao and shows him a letter from Cao Cao promising to make Han Sui Marquis of Xiliang if he captures Ma Chao and sends him to Xudu. Han Sui says that, having sworn brotherhood with Ma Chao's father, he cannot bear to harm him and will help him; he beheads Cao Cao's envoy and musters the troops of the eight divisions under him. Those eight divisions are Hou Xuan, Cheng Yin, Li Kan, Zhang Heng (張橫), Liang Xing, Cheng Yi, Ma Wan and Yang Qiu, and the eight generals follow Han Sui and, joining Pang De and Ma Dai under Ma Chao, march on Chang'an with a great army of 200,000 in all. Romance, Ch. 58 §11–13

The Xiliang army surrounds Chang'an. When a fire breaks out inside the city gate at night, Pang De beheads Zhong Jin, Zhong Yao's younger brother, who has been guarding the west gate, cuts through the bars and lets the troops of Ma Chao and Han Sui into the city, and Zhong Yao abandons the city, flees and holds Tong Pass. Then Cao Hong, who has been holding Tong Pass in Zhong Yao's place, comes down from the pass in pursuit and is attacked from both sides by Ma Dai, Ma Chao and Pang De, and Cao Hong and Xu Huang abandon the pass and flee. The Romance does not name Cheng Yin separately in these battles. Romance, Ch. 58 §14 · 18–19 · 22–23

Cao Cao divides his army into three, crosses the Wei River and lands on the northern bank; along the river he builds walled roadways and digs pits lightly covered with earth. Han Sui says that Cao Cao has crossed the river to strike at their rear, and proposes that Ma Chao hold the camp while he himself goes along the river to fight Cao Cao; Ma Chao makes Pang De the vanguard and has him accompany Han Sui. Han Sui and Pang De, leading 50,000 troops, go straight to Weinan. Romance, Ch. 58 §40 · 45 · 47 · 49–50

When Pang De charges with over a thousand armored cavalry, men and horses alike fall into pits dug to trap horses. Pang De leaps out of the pit and cuts his way through the encirclement on foot, and on his way to rescue Han Sui, who is trapped in the middle of the encirclement, he cuts down Cao Yong, a subordinate general of Cao Ren, takes his horse, rescues Han Sui and flees to the southeast. Ma Chao comes out to meet Cao Cao's pursuing troops, routs them and rescues the greater part of the army. When they return after fighting until sunset and count their men and horses, they have lost the generals Cheng Yin and Zhang Heng, and more than two hundred men have died in the pits. In the Romance Cheng Yin's name appears only in the listing of the eight divisions and in this passage. Romance, Ch. 58 §50–51 · 13
