Le Van Tuan's title fight became the main highlight at LION Championship 30, when the champion successfully defended the title against opponent Tran Trong Kim.
Right from the first attacks, Van Tuan imposed the game with strength and control ability. In the 2nd round, Van Tuan finished the match with a hand lock (armbar), closing the convincing belt defense.

In the remaining matches, many matches ended early, especially in the 52kg category. Nguyen Ngoc Phu won a technical knockout victory over Nguyen Thanh Nam after 2 rounds, with the highlight being a high kick that caused the opponent to be knocked down before asking to stop competing.

Le Hoang Duc also did not take long to overcome Trinh Thanh Cong. After a high kick that caused the opponent to fall to the floor, he completed the victory with a foot lock, thereby winning a ticket to the semi-finals.

Nguyen Huu Nghia made a difference right from the beginning of the match when he quickly brought Nguyen Van Thanh to the floor with a double wrestling move. From the back control position, he closed the match with a neck-pulling blow after only a few minutes.

Le Cong Nghi continued to extend the early finishing streak when he overwhelmed Au Van Hien. The boxer born in 1994 controlled well in the first round with standing attacks and wrestling defenses. In the second round, when the opponent tried to pull the match to the floor, Cong Nghi reacted effectively, forcing the referee to stop the match.

The match between Do Nguyen Minh Quyen and Le Van Vu was a rare match that had to be decided by points. Minh Quyen maintained a safe playing style, combining blocking when standing and knocking down at the right time to control the game.

In his return, Tran Ngoc Lam won against Nguyen Quoc Bao after the opponent's forehead was deeply torn and unable to continue playing.
Du Van Thuan closed the series of matches with a victory over Nguyen Hop Hai. He controlled the game with overhead kicks and handling on the floor, before the kicks into the supporting leg in the 2nd half caused the opponent to lose the ability to move, thereby extending the winning streak.
