Who Plays Cheong-San In All Of Us Are Dead?

The role of Lee Cheong-san is played by Yoon Chan-young. Yoon began his career at a young age, getting his first credited role at age 12 in the romantic television drama series "When A Man Falls In Love," according to his MyDramaList profile. On the show, Yoon plays the younger version of Lee Jae-hee, who is played as an adult by Yeon Woo-jin. The "All of Us Are Dead" actor returned to the small screen in 2013 with "Monstar," a musical series where he plays the younger version of Jung Sun-woo alongside Kang Ha-neul, who plays the older version.

2014 brought Yoon's first starring role, in the children's detective series "Pluto Squad," where he plays Lee Woo-jin, one of a quartet of intrepid kid detectives. Yoon followed that up with another lead role, this time in the TV drama series "Mama," where he plays Han Geu-roo, whose mother, Han Seung-hee (Song Yoon-ah) is determined to get him to be part of his biological father's family when she discovers she has a terminal illness.

Yoon, however, continued his streak of playing the younger version of established characters, appearing in shows such as the romantic drama "Gap Dong" and the historical drama "Six Flying Dragons." 2019 saw Yoon appear in another lead role, this time in the high school romance series "Everything and Nothing," where he plays Go Min-Jae.

"All of Us are Dead" is currently available on Netflix.
