PlayMusic regarded the album as another representative work of Tsai, noting that in terms of costumes, stage design, and choreography, she delivered a completely fresh presentation that fully showcased the high production quality of Mandopop, further raising anticipation for her future projects. The review also highlighted that the album successfully balanced both entertainment and musicality. In particular, it praised Tsai's significantly improved live vocal performance—whether performing upbeat or slow songs, her vocal expression, rhythm, and emotional delivery were more effortless than ever. The entire show also demonstrated a smoother and more cohesive approach to musical arrangement and reinterpretation.^[14]

The following is the track listing for the Blu-ray version, while the DVD version is divided into two discs, one for tracks 1 to 21 and one for tracks 22 to 34.
