Chen is a student and cheerleader at Ninjago High School.

The LEGO Ninjago Movie
Chen and a couple of cheerleaders see Lloyd and his friends and show their new cheer called "Boo, Lloyd". Lloyd sarcastically replied that they have a #1 hit on their hands, but they take it seriously and soon sang it on the radio. He is later seen near the end of the movie among the surprised civilians when Lloyd revealed himself as the Green Ninja.
