For 15 years, Helly Tong, whose real name is Tong Khanh Linh, has championed environmental values, green living, and sustainable development through both personal content and community projects.

In 2018, she co-founded Lai Day Refill Station, which specializes in providing eco-friendly household and personal care products. Subsequently, she took on a communications role at Song Foundation, helping to bring issues of waste reduction, sustainable consumption, increasing green spaces, and disaster resilience closer to young people.
