In episodes 20 and 21 of "The Wind Across the Blue Sky", Truong's character appeared and was predicted to have a difficult love story with Ngan (Viet Hoa).

In the original version of "30 Is Not yet the End", Truong's character is Luong Chinh Hien (ma Chi Uy) - a finance minister but with an aggressive version. With a flashy, generous appearance, Luong Chinh Hien easily conquered Man Ni (Giang So Anh) at first sight. He often let her go to meetings with business partners, making her more confident.
While in love, Luong Chinh Hien's long-time girlfriend came and exposed the bad guy. Accordingly, Luong Chinh Hien is truly a legitimate playboy when worshiping Buddhism without constraints, having relationships with many girls at the same time and his long-time girlfriend is also the one who will "clear up" his achievements.
It was her relationship with Luong Chinh Hien that defeated Man Ni, despite being an independent and powerful person.
In the Vietnamese version of "The Wind Across the Blue Sky", Truong is the owner of a 5-star yacht and also introduces himself as a person afraid of love.
However, the appearance of this character has caused a lot of controversy since its appearance. If in the original, Ma Chi Uy clearly depicts an old, trendy and experienced Luong Chinh Hien, then Denis Dang brought a youthful version that made him seem unattractive compared to the original.



Denis Dang's appearance is considered too young compared to Viet Hoa and does not give the audience the feeling that the two will be a couple.
Before the controversy, Denis Dang said he had read a lot of the audience's comments. "I really appreciate the feedback because I am most afraid that the audience will not even criticize me. I will cherish any comments and use them as luggage to gain experience and continue to try to improve," the actor confided.
