The documentary project, directed by Kawaii Tuan Anh, was released exactly 3 months since Duc Phuc was crowned the Champion of the contest " Intervision 2025". This is considered an important milestone in Duc Phuc's career.

Sharing in the documentary, Duc Phuc said that the victory at Intervision 2025 was not his personal efforts but the result of a team behind him: This victory is the result of nearly 50 people, who worked for 80 days with more than 40 meetings and costed up to billions of dong to prepare for an impressive 3-minute explosive performance at Intervision 2025s stage.

The male singer admitted that he felt pressured to represent an entire music industry. However, he decided to change his entire journey: This is definitely a thousand-year opportunity that only once to spread Vietnamese music to international friends.
One of the notable highlights of the documentary is the formation of the performance "Phu Dong Thien Vuong" - a performance with a strong Vietnamese cultural imprint that helped Duc Phuc conquer the international judges and audiences.
As for musician Ho Hoai Anh, who accompanied Duc Phuc from the early days of The Voice, he also shared: "10 years ago, I worked with Phuc in The Voice. Still thinking that after 10 years of change, Duc Phuc is still not fully equipped but still passionate and enthusiastic like a newborn child in the profession. That is also a good thing.

Not only the Vietnamese team, the representative of the organizing committee of Intervision 2025 also gave many compliments to Duc Phucs working spirit: I am really impressed with Duc Phucs discipline. The way he focuses on work, steps onto the stage to perform correctly and remember every small detail. The best thing is that after everything Duc Phuc had arranged in mind, he just needed to step onto the stage and enjoy his performance.
The documentary also revealed details that were first published because behind the sublime moments was a time of preparation that was so tense that it sucked their breath. Duc Phuc said that he had to practice singing, dancing, physical training and handle a series of requirements arising in a short time at the same time.
The male singer admitted that "Phu Dong Thien Vuong" was the biggest challenge ever, sometimes he was afraid that he could not reach the necessary high notes. There were moments when Duc Phuc even had to run into the bathroom to cry because he was overloaded.

In that moment, my heart was filled with two very clear words, Homeland and Vietnam. All of them seemed to lift their spirits. I am sure that I cannot give up and must do my best for my teammates and the country" - Duc Phuc said.
