In Chapter 103 of the Romance, Zhuge Liang, encamped at Wuzhang Plains, challenges the Wei army to battle, but it does not come out, so he sends Sima Yi a woman's headdress and white silk clothes along with a letter. Sima Yi accepts them with a laugh and asks the envoy only about Zhuge Liang's sleep and meals and whether his work is heavy or light. When the envoy says that the Chancellor rises early and goes to bed late, personally reviews every punishment of twenty strokes or more, and eats no more than a few sheng a day, Sima Yi says that he eats little and works much and cannot last long. Romance, Ch. 103 §38–40
When the envoy returns and reports this, Zhuge Liang sighs that Sima Yi knows him well. The Registrar Yang Yong remonstrates that there is no need for the Chancellor always to examine the registers and documents himself. Government has its proper structure, he says, and superiors and inferiors must not encroach on each other's work; if a household has its manservants till the fields and its maidservants handle the cooking, the master need only rest on a high pillow, eating and drinking, but if he does every task himself, his body will be worn out and his spirit exhausted, and in the end he will accomplish nothing. Romance, Ch. 103 §41–42
Yang Yong goes on to cite the old saying that those who sit and discuss the Way are called the Three Excellencies and those who rise and carry it out are called the gentlemen-officials, along with the stories of Bing Ji, who worried only about an ox panting, and of Chen Ping, who said that the amounts of money and grain had their own officials in charge, and he says that Sima Yi's words are truly the most apt. Zhuge Liang weeps and replies that it is not that he does not know this, but having received the weighty charge of the late emperor's entrusting of the young ruler, he only fears that others will not give their whole hearts as he does, and all present shed tears. Romance, Ch. 103 §42–43
This scene is the only place Yang Yong appears in the Romance. After this, Zhuge Liang feels that his spirits are uneasy. Romance, Ch. 103 §44
