The song continues a series of family-themed songs that have made their mark in their careers such as "Going Home", "Bringing Money to Mother", "Home's Taste". If previous compositions mainly depicted the image of mothers, this time, Den for the first time chose the perspective of a father to tell a story about responsibility, sacrifice and silent love.
Through the song "Big Job", Den honors men who are doing a particularly great "work" - being fathers, persistently working to raise children and build families. The song has Den's familiar narrative color, with close, sincere lyrics, evoking sustainable values in life.
The song is built according to three layers of emotions, reflecting the changes in a man's life when becoming a father. At the beginning, Den portrays the image of the pillar "rushing into life to earn a living", but no longer making a living for himself but to "bring rice home for the children". Personal dreams are gradually put aside, giving way to simple wishes: children to eat full, sleep peacefully and grow up in love.
Not idealizing the role of father, Den frankly admitted the initial difficulties with the rap line "Initially practicing being a father, it was terribly difficult". From a young person who only cares about himself, the lyrical character gradually transformed into someone who shoulders family responsibilities, learns to give up old habits, face pressure and grow up.
In the next emotional layer, the song expands to the perspective of a child who has become a father, thereby deeply understanding the hardships of parents. The image of parents "regardless of factories, construction sites, crowded streets, remote fields" or "reducing eating and clothing to have extra money for children during Tet" becomes a symbol of almost absolute love.
The song "Big Thing" closes with Den's own reflections on the journey of maturity. From a young person who was once struggling and precarious, Den looks back at himself in the role of a man who knows how to face and shoulder the burden. The image of a father "practicing crawling, practicing walking, practicing speaking" with his child evokes a beautiful cycle of life, where children are not only nurtured but also help adults learn innocence and love.
