The most famous actors, the greatest performers, and the most popular figures in the entertainment business walk through a door on stage—the “Hot Door”. Viewers hold their breath as they wait to see who would be walking through the door each night. On this stage the audience can see the artists’ different sides. Every night, the most popular figures in the entertainment business incorporate the hottest topics and current events into a spectacular variety show. The five hosts, Jacky Wu, O.D., Hank Chen, ADA and LuLu, who are different in age, generation, and hosting style, not only can sing, act, dance, and imitate, but are also skilled in cross-talk.
