An Investigation into Wei Yan's "Opening the City to Welcome Liu Bei": The Surrender in Hanzhong in Romance of the Three Kingdoms

Brief Introduction

In the circulation of Romance of the Three Kingdoms, the plot regarding Wei Yan's first encounter with Liu Bei is often summarized as "opening the city to welcome Liu Bei". However, strictly comparing with the original text, this expression is actually an artistic generalization of Wei Yan's surrender to Liu Bei during the Hanzhong Campaign. Wei Yan was originally a subordinate of Liu Zhang, later following Zhang Lu to guard Hanzhong. When Liu Bei attacked Hanzhong, he chose to submit after his superior Yang Hou was defeated. This turning point was crucial for the Shu Han regime.

Core Knowledge Points

* Character Background: Wei Yan was originally a general under Liu Zhang, later stationed in Hanzhong with Zhang Lu. He did not actively "open the city" from the beginning.
* Nature of the Event: It was actually a surrender after defeat. When Liu Bei besieged Hanzhong, Wei Yan's commander Yang Hou was defeated. Seeing the situation was hopeless, Wei Yan led his troops to surrender.
* Historical Significance: Wei Yan's joining provided Liu Bei with a general familiar with the terrain of Western Sichuan, which was key assistance for him to seize Yizhou.

Connection with Book Content

In Chapter 68 "Liu Bei Attacks Hanzhong" of Romance of the Three Kingdoms, this process is described in detail. After Liu Bei defeated Yang Hou, Wei Yan led his troops to surrender. The book does not describe him actively opening the city to welcome, but rather surrendering after the battle.

* Dialogue Details: After Liu Bei met Wei Yan, he asked about his ambitions. Wei Yan bluntly stated his willingness to lead five thousand elite soldiers to take the Ziwu Valley and capture Chang'an directly.
* Character Portrayal: This plot established Wei Yan's image as brave but arrogant, and also laid the groundwork for the future "Ziwu Valley Stratagem" and his conflicts with Zhuge Liang and Yang Yi.

Conclusion

Wei Yan's "opening the city to welcome Liu Bei" is more of a popularized interpretation of the Hanzhong Surrender plot by later generations. In the original work, this was Wei Yan's political choice based on assessing the situation, marking the stabilization of Liu Bei's forces in Hanzhong, and the starting point of Wei Yan's career in Shu Han.
