Many Vietnamese believe in the significance of feng shui and numbers, with the number 7 symbolizing creativity and breakthrough. From the seven life forces, seven-day weeks, Buddha’s seven steps with each step blooming seven lotus flowers, to 49 days, the number 7 always carries a special energy.

The number 7 appears in various aspects of life and sports. In handball, there are seven players per team, competing for 30 minutes to score goals. In the book market, bestsellers like “The 7 Habits of Highly Effective People” and “The 7 Secrets of Success of Young Millionaires” also highlight the number 7.

Psychology professor George Miller discovered that human short-term memory consists of about seven elements, known as “The Magical Number 7.” In feng shui, seven swords (Thất Kiếm) are used to ward off evil spirits, and arranging seven items in the home is said to create mysterious power.

In basic mathematics, 999,999 divided by 7 is exactly 142,857. The Clay Mathematics Institute offers a prize for solving one of the seven most challenging mathematical problems, and Professor Ngô Bảo Châu received this award in 2008.

Number 7 in Literature and Art

The number 7 also appears in literature and art, from the seven basic art forms to the seven musical notes creating various genres of music. In literature, there are stories like “The 7 Voyages of Sinbad” and the fairy tale “Snow White and the 7 Dwarfs.”
