In "The Tree of Life", Duong Tu plays Bach Cuc - a female police officer stationed in the highlands with a radiant smile and a slim, healthy figure. The actress said that she had to lose 15 kg and 188 days of continuous filming in the highlands to complete the role.
Revealing the secret to weight loss, Duong Tu revealed that she has adjusted her diet according to a scientific structure under the guidance of a nutritionist. Accordingly, her menu mainly includes boiled eggs, steamed fish and butter salad, almost no starch.

In addition, Duong Tu maintains a Pilates and boxing schedule of 2 hours each day. Her goal is clearly defined: to lose fat but still maintain muscle strength to respond to action scenes, absolutely avoiding weight loss that harms health.
Duong Tu is inherently a person who easily gains weight and has faced criticism, even being replaced for roles because of her figure in the past. The actress affirmed that this weight loss is not aimed at chasing after aesthetic standards, but is a purely professional choice.
The main setting of "The Tree of Life" is a wasteland at an altitude of about 4,800 meters. The film crew filmed scenes here for 188 days, with Duong Tu almost without makeup to maintain authenticity.
On screen, viewers can clearly see very real details such as rash due to reaction to altitude or signs of frostbite due to cold. In temperatures dropping to minus 25 degrees Celsius, the actress directly performed a series of high-intensity scenes such as gunfights and snow chases.
On the first day of filming, she suffered from severe altitude sickness and had to use oxygen to continue her work. However, Duong Tu resolutely did not use stunt doubles for dangerous scenes such as soaking in ice or close combat, so that the emotions and weight of the role could be fully conveyed.
The spirit of respect for the profession and determination for the role helped Duong Tu receive love and respect from the audience and colleagues.
