As seen in the last season, the competing singers performed on stage and the 500-member audience panel voted, deciding the outcome of the results.

Dimash Kudaibergen, Lion, Tia Ray and Diamond Zhang returned as guest singers for the Biennial concert on season six.

Tia Ray and Kudaibergen appeared as guest assistant singers during the finals for season seven.

Ray and Jam Hsiao (of the Lion band) returned as contestants on the eighth season.

Outside Singer, Kudaibergen also appeared in CBS's reality competition The World's Best in 2019 where he withdrew after the Top 12 rounds.

Cheung's appearance (with the exclusion of a shot with him and Teresa Carpio) and performance were unaired and edited out of broadcast.

Tan withdrew from the competition after the Knockout episode aired, and results of her scores were displayed in grey text.

The winner was determined based on the combined number of votes accumulated during the semi-finals and the finals.

Before the final results were announced, the host named Kudaibergen, Lion, Lam, and Li as "Ultimate Winner Candidates".
