Answer
ER, the long-running medical drama, served as the final platform for Ming-Na Wen's portrayal of Dr. Jing-Mei "Deb" Chen. Wen's character made her debut in the pilot episode and remained a central figure throughout the series' 15-season run. With ER drawing to a close, Wen's departure marked the end of an iconic character's journey, leaving a lasting impact on both the show and its devoted fan base.
