Thu chose the idea of sending a letter to a baby girl born while her mother was treating COVID-19 at the Central Hospital for Tropical Diseases. The letter described the hardships of the doctors and pride in their contributions to the prevention and control of the pandemic in Vietnam.

Dao Anh Thu's letter has been translated into French by the organizing committee to submit to the Universal Postal Union in Switzerland for the international competition.

The UPU International Letter Writing Competition 2021 was organised by the UPU with the theme: "Write a letter to a family member about your experience with COVID-19."
