The movie "The Heart of the Heart" on February 7, 2025 (the 10th day of Tet) brings a gloomy atmosphere with an ancient, somewhat desolate setting, arousing curiosity for the audience about the story that will be told in the movie.
The film was released in the context of "The Four Guardians" by Tran Thanh and a series of famous films with hundreds of billions invested are dominating the box office.
However, the soul lamp quickly attracted the attention of the audience with images, sounds and a mysterious story about the soul lamp.

The film tells the story of Thuong, a woman whose husband is away from the army, raising her son - Linh alone.
One day, Thuong accidentally picked up a mysterious lamp, which immediately attracted Linh's curiosity. The soul lamp becomes a connection between the underworld and the positive world, bringing fears and mysteries that have never been solved.
Director Hoang Nam said: After more than 10 years of traveling, exploring and coming into contact with spiritual stories, now I want to create a film that is not only about spiritual issues but also bears the strong imprint of Vietnamese culture. "The Light of the soul" is a journey to discover oneself, maternal love and traditional values of the nation".

On February 18, according to Box Office Vietnam, "The Heart Light" achieved a revenue of over 100 billion VND.
A quite interesting point in this work is the setting chosen by the film crew. Co La Waterfall is located in Chi Vien Commune, Trung Khanh District, Cao Bang Province, where director Hoang Nam chose to film most of the scenes.
From Trung Khanh town to the center of Chi Vien commune, visitors along the concrete road through Na Mu hamlet, passing Thoong got Hydropower Plant about 1km will see the traditional stilt houses of the Tay people in Ban Ruoc hamlet to Co La waterfall.
The waterfall is about 30m high, with three layers of clear blue water, pouring down like a harmony between the quiet mountains and forests. This place is likened to "minorized Ha Long Bay" with a beautiful scenery like a water-culture painting. The beauty of Co La waterfall is likened to the daughter of the mountainous region with its strongness but wildness.


On February 19, speaking with reporters, Ms. Phuong Thi Thanh (Trung Khanh town) - shared: "Co La waterfall has been famous for its beauty for a long time but is still not famous from near and far, only occasionally, but blogger film when coming here to travel but it is not as effective as a budget. Hopefully, the film The Heart Light filmed here will help Co La waterfall as well as Cao Bang become famous, more tourists know it".
Mr. Sam Viet An - Director of the Department of Culture, Sports and Tourism of Cao Bang province - said: "After creating conditions for film crews to produce, localities also need more resources and projects to communicate and promote the beautiful image of the locality".
"At a suitable time, the director and actors returning to Cao Bang to promote the film and interact with the audience... may help promote" - Mr. Sam Viet An added.
