Lord Changwen, known as Mi Dian, holds the vital position of Chancellor of the Left in the Qin government. His path began on the battlefield under King Sho, commanding a specialized 100-man unit executing high-risk missions. This elite force provided critical support to commanders like Ou Ki and Kyou, with Ou Ki specifically tasking Changwen to mentor the young Kyou and refine her grasp of tactical details.
Transitioning from military command to the court, his loyalty and expertise propelled his rise. He played a pivotal role in ensuring King Ei Sei's survival during the Sei Kyou rebellion, masterminding an escape using a body double (Hyou) and personally intercepting an assassin targeting the king. His political influence solidified upon his appointment as Chancellor of the Left in 239 B.C., a position achieved after Ei Sei strategically released political prisoners to strengthen their faction.
Despite his high office, Changwen remained deeply engaged in military strategy. He commanded the west wall defenses during the intense Battle of Sai in the Coalition Invasion and later served as one of the four chief strategists planning the critical Gyou campaign. His military acumen, including frontline combat experience and skill with the glaive and bow from King Sho's era, was acknowledged by contemporaries like Shou Hei Kun.
His capabilities blend political and martial prowess:
- **Politics**: Consistently rated in the 90s (peaking at 96)
- **Intelligence/Knowledge**: Ranges from 86 to 92
- **Leadership**: Between 85–87
- **Strength**: 75–82, declining slightly with age but remaining formidable for a statesman.
Changwen's profound personal loyalty to Ei Sei defines him, often seen as the closest figure to a parental guardian for the king. This deep bond is illustrated in moments like his tearful reaction to learning of Ei Sei's impending fatherhood. Historically, he participated in quelling the Lao Ai rebellion, aligning with records in the ShiJi.
Beyond governance, he addressed Qin's chronic flooding by endorsing engineer Tei Koku's project in 243 B.C. He also personally trained the young Ei Sei in swordsmanship.
