Before 1990, the lifestyle of Vietnamese teenagers was largely family-oriented and influenced by traditional values. Most young people lived in extended households, where multiple generations shared their lives together. They had limited opportunities and often depended on their families for guidance. However, since the 1990s, there has been a significant shift. Teenagers have gained more independence and access to information, allowing them to pursue their interests and ambitions. The rise of technology has created new trends in fashion and communication, leading to a lifestyle that is more westernized and diverse. While privacy has become increasingly important, the strong sense of family remains a vital part of their lives.
