Over the years, he has seemed to be facing a long series of slide in his career, when the six films he starred in in a row all had poor results, despite large investments and huge media campaigns.
Starting with Truong An Na (2020) with an average of only 7 million views/episode, Thanh Nghi continued to be stuck in similar historical roles in Du Quan Ca (2021) reaching an average of 6 million views/episode. In 2023, "The Wind of Man Understands My Heart" changed to a modern romance genre but did not create a breakthrough, only maintaining 10 million views/episode.
Two years later, Deeply Power (2024) and Pho Son Hai (2025) were promoted as key projects but still only reached about 10 to 25 million views/episode, ranking 19th in the online film rankings in 2025.
The latest film "Thien Duong Cac Tam" (formerly known as "Ho Yeu Tieu Hong Nuong - Vuong Quang") is expected to be "expired" for the actor.
Initially, the project achieved many achievements, and the actor was also recognized for his acting efforts. However, the film is currently at risk of becoming the lowest-viewed work in the entire project series "Ho Yeu Tieu Hong Nuong".
While previous parts such as "Nguyet Hong" and "Hoai Thuy Dak Dinh" average 14 to 17 million views/episode, Thanh Nghi's part only kept 13 million and could reach 15 million views.
Experts say that consecutive failures do not come from taste but also from the lack of breakthroughs in script, production and acting. Many audiences believe that although the team continuously uses the "ball-scoring" tricks of fans buying VIP packages to increase initial views, to boost the discussion heat on online platforms, the quality of content is the deciding factor. A film can create a "wave" in the first few days, but if the plot lacks appeal, the dialogue is disjointed and the actors are not interested, the audience will quickly turn their backs.
Currently, Chengyi is considered a typical example of the "short-p going" situation of many Chinese historical stars. After this "long slide", fans expect the actor to make a real change.
