Rosalind Chao played Arnold's teacher, Miss Chung, in seven episodes during Seasons 4 and 5 on "Diff'rent Strokes." Chao, who had previously appeared in Season 3's "Almost American" as an immigrant hoping to gain American citizenship, logged time in one of the series' most memorable episodes: "The Reporter," in which Arnold's discovery of drugs at his school somehow brings then-First Lady Nancy Reagan into the episode to pitch her "Say No to Drugs" campaign.
A regular on episodic television and in features for five decades, Chao is perhaps best known to small screen audiences as Soon-Lee Klinger, wife of Jamie Farr's Corporal Klinger, in the finale of "M*A*S*H" and its short-lived follow-up series, "AfterM*A*S*H," as well as botanist Keiko O'Brien on "Star Trek: The Next Generation" and "Deep Space Nine." More recently, she's appeared on episodes of "Hawaii Five-O," "Better Things," and "The First Lady."
Chao's feature film credits range from Jackie Chan's American feature film debut, "The Big Brawl" to "The Joy Luck Club" and Stephen Soderbergh's "The Laundromat." In 2020, she played Mulan's mother in the Disney live-action version of "Mulan," and co-starred with Melissa McCarthy the following year in "The Starling."
