In episode 3 called "Child outside the Family", members of Running Man team have to participate in games to find clues about 2 children who are not related by blood hidden in the group.
The first challenge is called "Fake Heir" with a game combining the physical strength and ingenuity of each member. Then challenge "Pries of a Silly Sink" with the game "Crunch your tongue 7 times before you speak". At this time, 1 member of each team will hear the slang in Vietnamese and explain in English so that the remaining members can guess the correct answer.

At the end of each interesting challenge, the members of the winning team will receive suggestions to find a child outside the family.
Notably, in the third challenge called "The Last turn-off", each team had to send representatives to participate in a combat game called "S spring hands". This is a fairly familiar game in Running Man. Accordingly, the two were forced to stand opposite each other, each pushing the other one by one, until the other fell and winning from behind.
In this competition, Anh Tu Atus and Quang Trung were chosen to compete in the same pair. The result was quite surprising when Quang Trung easily pushed his junior down after just a few attempts.

At first, Anh Tu himself was very surprised when Quang Trung pushed him down. The male singer showed disbelief and determined to take revenge for the second time.
However, Quang Trung once again defeated Anh Tu Atus, forcing him to sadly accept defeat.

Meanwhile, Quan A.P - Trang Phap is the only couple of the opposite sex participating in the competition. The male singer was praised for his tact when he did not deliberately use his strength to knock down his senior. In the end, both agreed to stop the game with a draw.

At the end of episode 3, the members entered the final challenge called "Discovery of the truth". Here, the last two illegitimate children were revealed.
Let's watch the next episode of Running Man 3 with interesting and attractive challenges at 8pm every Saturday.
