After episode 10 of Say Hi Beautiful Sister aired, the results of the performance rankings became a topic of debate on social networks.
In particular, Chau Bui was heavily criticized for showing his insensitive attitude when hearing the news that his team still kept a hot seat, defeating Bich Phuong's team.
When MC Tran Thanh released the song "Bac thang len hoi anh troi" by Bich Phuong's team, it could not surpass the song "Chua phai anh dau", Chau Bui celebrated by shaking his hips and squeezing his tongue at the opponent.
Her actions received mixed opinions. The audience thought that while singers Orange, Phuong Ly, Vu Thao My, 52Hz hugged each other, Chau Bui provincecated the opposing team, pretending to be too happy.
She was even criticized for being on the same team as My My (Bich Phuong's team) but not showing respect for her colleagues in the result of winning and losing.
Meanwhile, members of Lam Bao Ngoc's "Duyen" team, when defeating the "Cach yeu dung dan" team, rushed onto the stage to comfort their colleagues.
Phuong My Chi continuously praised the performance of Bich Phuong's team, while Phao and the members knelt down on the catwalk to show respect for the efforts of Bich Phuong, Juky San, Quynh Anh Shyn, My My, Lamoon.

In performances such as "Run", "So Nam", "Chot Phai Anh Doi" or the dance competition, Chau Bui was criticized for being too tongue- Talking, often blurring the words, and not restraining his expressions.

Chau Bui also caused controversy for constantly mentioning that he had studied vocal music for 6 years. However, the weak, unclear voice of the 9X model has not yet convinced the audience.

Chau Bui's singing and dancing ability is not too outstanding in the 30 "beautiful sisters" squad. In the song "AAA", Chau Bui was the least singer in the group, with 1 line of music in just 2.2 seconds.
Chau Bui was once ranked last in livestage 2 and was almost eliminated. After that, when Ly Han invited Chau Bui to join the team, she frankly said "I want to save Chau because I'm afraid she's going to be eliminated".
