The song "Dau xe bo" was composed by DTAP, inspired by the short story " Vo du" by writer Kim Lan. Previously, Phuong My Chi included this song in the MV released in June 2023, which was commented to be a breakthrough in its cheerful image and melody.
Phuong My Chi's opponent at the Singapore station is male singer Vuong Hoang Hao from China. He chose the R&B song, overwhelmingly winning Phuong My Chi with a score of 20-3.
Vuong Hoang Hao became the "king of Singapore stations", and was also the first Chinese contestant to head the station in Sing! Asia 2025.
Controversy broke out after Phuong My Chi's performance was "shocked" by the Chinese singer. Many Vietnamese audiences praised "Chi Bay's" performance, proud that the female singer brought the beauty of Vietnamese culture to promote and interact with friends around the world.
Many opinions expressed regret for Phuong My Chi at this competition station. Some audiences think that there is a certain favor for contestant Vuong Hoang Hao.
In the face of heated debate on social media, Phuong My Chi's manager gave her opinion.
We have determined from the beginning, in Sing! Asia and My Chi have two tasks: Bringing Vietnamese culture to the world and going as far as possible to reach the finals.
Speak a little about the program format: If you win the previous round, you have reached the quarter-finals. And in the next round, you will go to the next stage to meet the winner of that stage, the issue of winning or losing is no longer so important, and cultural exchange, bringing culture to the world is the priority goal.
When you are safe, it is important to have a reasonable energy distribution strategy. The goal is to win the whole battle, not a single match.
Despite losing, Phuong My Chi still got a ticket to the quarter-finals in Hong Kong (China) because she won at the Vietnamese station.
