The sixth season of the Chinese reality talent show Sing! China premiered on 30 July 2021, on Zhejiang Television. Li Ronghao returned as coach for his third consecutive season. Former coach Wang Feng returned to the coaching panel after a four-season hiatus. Na Ying also returned after a one-season hiatus, but only as a coach during the blind auditions and was later replaced by Liao Changyong. They brought along Hacken Lee who is a new coach this season, replacing Li Jian, Nicholas Tse and Chris Li from the previous season.^{[1][2][3][4][5]}

On 15 October 2021, Wu Keyue was announced the winner of the season, marking Hacken Lee's first win as coach. Wang Jingwen, Chen Wenfei, Yao Xiaotang, and Kazu finished runner-up, third, fourth, and fifth places, respectively. With Keyue's win, she is the first person to receive all turns from coaches in the blind auditions and win the competition. Additionally, for the first time in the show's history, all finalists were female.

Only Li Ronghao returned from the previous season. Li Jian did not return for Season 6, making room for the return of Wang Feng after a four-season hiatus. Na Ying also returned after being absent from the previous season. However, she only participated in the blind auditions, leading to Liao Changyong replacing her afterwards. These coaches were joined by first-time coach Hacken Lee. Therefore, Nicholas Tse and Li Yuchun have been confirmed to leave the show. The host remained the same as last season.

This season introduces teaching assistants. Coaches Na Ying, Wang Feng, Li Ronghao and Hacken Lee will team up with assistants Zhang Bichen, Huang Xiaoyun, Jike Junyi and Momo Wu respectively. Teaching Assistants function like normal coaches. However, when it comes to recruiting contestants, the final decision is up to the coach on whether or not they want the contestant on their team. In other words, the contestant cannot be recruited to their team unless the coach presses their button. If the teaching assistant pressed their button but not their coach counterpart, then the coach has the last 30 seconds to decide if they want the contestant after the song finishes. While there is a 30-second countdown, if the teaching assistant is really impressed by an artist's performance, they can choose to use their Instant Recruit ability. This means that the teaching assistant can press their button again, causing the chair's voice system to say "I WANT YOU" and the respective coach to instantly turn around. This also makes their team available for the artist to choose. However, this action can only be done once per team.^[6][7]

In this stage, the coaches are to recruit a total of six artists to form a team of their own, contrary to five in the previous season. The forming of the teams would move to a format that is similar to the "Six-Chair Challenge" featured in the British version of The X Factor. Once a team is full with six artists occupying all the spots, the subsequent artists which the coach has successfully recruited would have to face-off with one of the six artists in the sing-offs for a spot in the team.

The incoming artist may select any of the six defending artists to compete against in the sing-off, and both artists would each sing a new song and the coach would decide on the winner. The winner would be given the spot in the team. However, continuing from last season, the losing artist has the chance to be saved by other coaches (the same function as the steals from The Voice. The coaches are given 10 seconds to save the losing artist for elimination. If one coach presses their button, he/she will be automatically on the new coach's team and if more than one coach presses, same as with the blind auditions, the artist has the opportunity to choose which coach they want.

For defending artists, once they have won a sing-off against an incoming artist, they would receive immunity from the subsequent sing-offs and immediately advance to the next round of the competition.

In this round, coaches will draw to determine when they will have the power to choose first. That coach will choose an artist from his team and state which opposing team he wants that artist to face off against. The chosen artist from the representative team will decide his/her opponent by draw as well. Each coach is allowed one block in this round. If a coach used a "Block" on his artist, he/she may not face a certain artist from another team by default. At the end of each Cross Knockout, the two artists will receive votes of approval from a 51-person judging panel. The artist with the most votes will advance to the Playoffs, while the other would be eliminated.
