On YouTube channel, the producer of "Anh trai say hi" posted a behind-the-scenes video of episode 1, about the "DNA test" room.
That was the moment when 30 new contestants entered the competition and had their first greeting with the audience.
However, many people discovered that this video had all 29 "brothers", only Vu Thinh was missing. Some of Vu Thinh's fans asked the producer to explain and apologize to the singer for this mistake.
Previously, "Anh trai say hi" was continuously accused of being unfair, causing the artists to suffer.
When the concert took place on September 29, the audience discovered that the large outdoor poster of the show was missing a picture of singer Cong Duong. The organizers' omission made the audience angry and they continuously asked the crew to make corrections.
During the show, Captain, despite making it to the finals and participating in the production of many songs, only appeared in 3 performances, equal to those who were eliminated early such as Thai Ngan, Do Phu Qui, Hai Dang Doo...
Captain's team in the 4th competition night was also the only team that was not allowed to perform any songs in the concert.

Negav's incident made the second night of the show a hot topic. Many viewers questioned whether the rapper would return amid a wave of harsh criticism from the public.
Many brands that the male rapper collaborated with were asked to remove posts and cancel contracts with the rapper, otherwise the audience would unfollow them and even call for a boycott of the brand.
On the contrary, some of Negav's fans said they were no longer interested and wanted to cancel their tickets to the second show if their idol was absent.
In recent days, the show's producers have also been criticized for staying silent and not taking any action in response to Negav's controversy. It is still unclear whether the rapper will appear at the second concert, but he has canceled all his schedules and locked his social media accounts.
The concert "Anh trai say hi" brings together 30 contestants and famous guests. Ticket prices announced by the organizers range from 500,000 VND to 10,000,000 VND.
