The 17/10 broadcast introduced five Group C characters: Bo Sua Achu, Cao Boi Lang, Heo Ma Hong, Lion Vui Tuoi, and Khi Xu Mi. Tran Thanh and Bich Phuong served on the advisory board, joined by guest advisors Bao Anh and Tang Duy Tan.
Suspended on a swing, Heo Ma Hong performed "Cam ky thi hoa", a song previously popular on Em xinh say hi 2025. The new arrangement, blending rock with folk elements, allowed the singer to display a powerful, emotional voice. The advisory panel rose to applaud as the mysterious vocalist reached high notes and shifted vocal tones.
Guest advisors noted Heo Ma Hong's identity remained an intriguing mystery. They believed the performer could adapt to various styles, making predictions uncertain. Tran Thanh praised Heo Ma Hong's expertly handled vocals, suggesting professional training. He suspected the character deliberately altered their voice to mislead listeners.
Tang Duy Tan believed the masked performer was an experienced vocalist on major stages. Bich Phuong initially considered veteran singer Thanh Lam but found it "increasingly difficult to determine" the identity. Advisors speculated on names like People's Artist Thanh Hoa and singers Duong Hoang Yen, Thanh Ngoc, and Ngoc Khue. On digital platforms, audience guesses included Anh Tho, Hoa Minzy, and Phuong My Chi.
Cao Boi Lang also puzzled listeners in episode three. Performing "Mat ket noi" by Duong Domic, he displayed a high, husky rock voice. Advisors expressed confusion because Cao Boi Lang's speaking voice during interactions sounded feminine, contrasting with his masculine singing voice. Bich Phuong noted Dam Vinh Hung on her prediction slip but lacked confidence. Show data indicated Cao Boi Lang had won multiple awards and experienced a hiatus before returning to music.
