Considered the film with the most open and free space ever by director Luong Dinh Dung, the film crew of "Doi Ha Co" travels from the South to the North to find a filming location.
It is estimated that this journey of the crew is more than 20,000km long and will last about 3 years to find original, aesthetic scenery that has not been exploited for tourism too much in Ninh Binh, Thanh Hoa, Hanoi and Son La.
Ban Bu Cave, Thanh Hoa
Nearly 200km from Hanoi, Ban Bu Cave (Thanh Hoa) is a special filming location that the film crew spent a lot of time surveying and exploring. The cave is more than 1km long, the inside is damp, windy and there are flooded sections that force the group to move by boat to get deep inside.
Not only possessing a wild beauty with a unique system of stone cages and stone mortar, formed over millions of years, resonating with the deep underwater corridor creating a mysterious and enchanting landscape, this place also contains many harsh elements - even being able to see pets blooming during filming.

In particular, Ban Bu Cave was a military retreat of the Le Loi army during the Lam Son uprising in the 15th century, adding to the depth of history and mysterious colors of the film.
In addition to its natural beauty, Ban Bu Cave was chosen by director Luong Dinh Dung for a film because it has never appeared in any film. In the story of "Body Hill", this is where strange spiritual rituals take place, in harsh filming conditions.
Also here, the main actors have a scene of themselves immersed in cold water in the cold winter in the North - a haunting experience for them.
Moc Chau Old Forest, Son La
The road around the mountain that appears hazy in the mist is the image that the film crew has searched for all year round, across Ha Giang, Tuyen Quang, Dien Bien. Finally, the crew suddenly explores an old forest deep in Moc Chau, Son La.

This is a setting that has never been exploited by any filmmaker, with a wild and mysterious beauty with many hundreds of years old ancient monsters, and the mysterious atmosphere that the film aims for.
Linh Ky Moc Eco-tourism Area - Thanh Hoa
The characteristic of the film "Doi hanh bang" is the story associated with water, with many underwater scenes, making an impression with the film of a car carrying the character Ngu (played by Be Quyen) gradually sinking into the lake. This series of scenes was taken at the artificial lake in Linh Ky Moc eco-tourism area in Thanh Hoa province.

The weather in the last days of the year is usually below 10 degrees Celsius, watching a scene of yourself sinking into cold lake water is a stressful and memorable memory for the main actress Be Quyen.
Tam Diep pineapple grassland, Ninh Binh
The pineapple-growing grassland is full of resources, attracting travel enthusiasts to check-in. The quiet, lonely beauty next to the bustling highway and trucks quickly caught the eye of director Luong Dinh Dung. He said that this setting evokes the feeling of being both near and far from the city, bringing an interesting contrast.

In Tam Diep pineapple grassland, the film crew built a car garage on an agricultural land of nearly 300 square meters, serving scenes related to the main character Bao.
With a large setting including many lands being explored for the first time, Luong Dinh Dung creates, aiming to bring a haunting cinematic experience that makes the audience feel shiverish from the first moments.
