On the 21st episode of the Channel S and E Channel variety show 'Nonscheduled Tour: Going All the Way!', Kim Dae-hee, Kim Joon-ho, Jang Dong-min, Yoo Se-yoon, and Hong In-gyu visit Yanji, China, to see Heaven Lake at Mt. Paektu and the Flying Dragon Falls. On this day, the members headed to the Heaven Lake observatory amid fickle weather. When the fog obscured the view, Kim Joon-ho expressed concern, but upon reaching the summit, the clouds cleared to reveal the scenery of Heaven Lake. Yoo Se-yoon remarked, "You have to make a wish here," expressing his admiration. Wanting to share the moment with their families, Kim Dae-hee made a video call to his wife and eldest daughter Sa-yoon, and Kim Joon-ho also called his wife Kim Ji-min to share the emotion. Kim Joon-ho then led the members in requesting a group photo. The group afterward moved to the Flying Dragon Falls, located at the foot of Mt. Paektu. In front of some 200 steps, Hong In-gyu worried about Jang Dong-min, whose knees were in poor condition, but Jang Dong-min climbed the stairs, saying, "Even if my legs hurt, I have to see the Flying Dragon Falls." Meanwhile, the 21st episode of 'Nonscheduled Tour: Going All the Way!' is scheduled to air on Saturday the 24th at 9 p.m.
