Peking Opera performances have been held in theaters worldwide since the early 1900s, but the ins and outs of becoming stage-ready remain less known. CGTN documentary "100 Days of Peking Opera" sheds a bright light on the behind-the-scenes of training for Peking Opera by following Beijing-based theater debutant Nadim Diab from Lebanon in his foray to cover the basics of the art, pick up a few head-turning moves, and put on a show in front of a live audience – all in 100 days.
