These days, the anniversary of the Liberation of the South and National Reunification Day is celebrated across social media platforms. Images of the red flag with a yellow star, archival footage, and short videos recreating history appear widely, drawing the attention of many young people.

In the context of the rapid development of the digital technology revolution today, social media is no longer merely a communication tool but has become an open space for the community to share and disseminate knowledge.

Digital transformation is creating a strong shift in the methods of preserving and spreading heritages. From the national archives to the museum and relic system, management agencies are proactively applying technology to preserve cultural and historical values ​​and bring them closer to the modern public.

The “Not Alone” online safety festival officially opened at Dong Kinh Nghia Thuc Square in Hoan Kiem, Ha Noi, on the afternoon of November 1 with the attendance of around 500 participants — including representatives of ministries, departments, international organisations, technology enterprises, students, and tourists.

Thanks to the support from digital technology, the tourism development provided the most convenient services to satisfy tourists.
