During his talk, the actor brought up his Chinese promotions for 'My Sassy Girl 2', saying, "Recently I appeared on a show called 'Happy Camp', which is a lot like 'Infinity Challenge' in Korea. The good thing about Chinese variety shows as opposed to Korean ones is that it only takes 3 hours of filming in a studio. With '1 Night and 2 Days', we film for about 35 hours and air for about 3."

The actor also added, "Another cool thing was the sound effects were in real-time. All those sound effects you hear on variety shows, they would play them at the most appropriate time on this show. I was so surprised. It was a whole new world." 

Maybe '1 Night and 2 Days' should try sound effects in real-time for their next filming!
