Trọng Hiếu Nguyễn (also known as Trọng Hiếu Trần Nguyễn) was born in Bad Kissingen, Germany on July 4th, 1992 and is a Vietnamese singer songwriter, actor and dancer.

When he was a young boy, he had the chance to meet pop star Britney Spears on German TV and even had the opportunity to dance in front of the star who gave the then young Trọng praise and encouragement (and a signed CD). The encounter was reuploaded by Trọng Hiếu on his official YouTube channel.

Trọng later went on to become a contestant on Vietnam Idol, where he won, and became a successful star in Vietnam.

In 2024, Trọng Hiếu rebranded under the name (S)TRONG, and would release a re-debut song by the name of “Rise Up Underdog”, which released in July the same year.

The new name holds a special meaning as the letter “S” represents the shape of Vietnam on the map, while the brackets embrace it tightly just like the love he has with his home country, where he has called home for many years since moving from Germany to start his career in music.

Trọng Hiếu can speak German, Vietnamese and English and has produced songs in all three languages.
