First of all, all the guests in the program are real, without any exaggeration or affectation. The guests are all very kind-hearted. This kindness is engraved in the bones, so the audience is not watching a reality show. More often, guests seem to be psychologists, sweeping away the haze in people's hearts.
Second, Luo pd is good at relying on the personality of the participants to find the highlights that seem boring but interesting. We all know that "personal design" is very common in variety shows. The personal design created by Luo pd for guests is actually himself, so the audience is not embarrassed.
Thirdly, he is very good at making stalks after three hours and three meals, such as Buffering ric, Dimples Blooming and Meng Dou Kong, which bring comparable effects to film editing.
