Thế hệ 9X (literally "9X Generation", often referred to simply as 9X) is a Vietnamese term for people born during the 1990s.
[2] They are often described as being more confident than members of older generations, they dare to freely pursue personal interests, and are more proficient in foreign languages.
Technology, specifically the internet, is an important part of their lives.
They are also willing to reject established traditions, ignore elder class values, listen to classical music, and follow foreign fashion trends and life styles.
This phrase was later popularly outshone by the term "Gen Z" which has a very close definition to the "2K."
