A Chinese satellite TV station, marking the show's tenth anniversary, invited the two Korean singers for a rare full hour appearance.
During the recording on Wednesday, the two showed a joint dance along with Hankyung's hip hop and traditional dances and a taekwondo demonstration by Siwon, to the applause of 800 audience members.
Tickets to the show's recording, randomly given out by drawing, were said to be sold for as much as 250,000 won.
The program will air nationwide on Aug. 18.
