The context of the fire in the coconut forest appears short in the teaser, standing out with the image of the family of three people and the villagers running in bombs.
The fierce war is shown with broken coconut trees, the houses are no longer intact and the bomb falls continuously as if they want to burn them all.
To find the scene, the crew has roamed many places. Not simply choosing a coconut forest area to build a scene, with director Ly Hai, this must be a true scene from that place.
Right from the script, Ly Hai described in detail the context and putting a lot of enthusiasm for the first time a scene of many historical properties.
Initially, the crew also found a number of areas with coconut forest in the Central region but it was not feasible, due to the location or not allowed to film, or not revolutionary historical.
After many searches, the location was chosen as Thien Nghiep commune, Ham Tien ward, Binh Thuan province.
Producer Minh Ha shared: "Right here, during the war, there were battles, bombing battles ...".

In a fire scene of live explosion, the crew did not use much to the technology of simulating CGI images, the preparation must be very careful, including the participation of fire experts to ensure beautiful scenes but still safe.
Director Ly Hai directly directed the scene, and held his breath to watch each "explosion" in a snap.
The two main actors who made this scene were actors Quyen Hua and Kim Hai, after filming Quyen Hua, she still felt afraid of the explosion from behind. Kim Hai could not imagine the scene was so honestly recreated.
