The singer's peak song in the fifth season is different from last season. It has always been the peak song every two years. This season's singer and last season's singer led the team, pairwise PK.
The peak of the fifth season is the form of three kings on the same stage. Instead of inviting singers from last season to form a team, we invited Coco CoCo Lee from last season, Han Hong from the third season, and Sandy Lam from this season to draw lots to become three teams for PK.
