The ancient Shan Tuyet Tea trees hold a strong sentiment with local people growing up in the area, so each villager always has an awareness to preserve them and considers them an indispensable part of their culture. Preserved, cared for and grown on mountains covered by cloud all year, the quality of Shan Tuyet Tea leaves are always pure and when used to make tea deliver a delicious fragrance, thanks to these features Shan Tuyet tea has been considered as characteristic of Cao Bo tea region.

Being recognised as a Vietnamese natural heritage contributes to protecting the genetic resources of the well-known tea variety. Meanwhile, the event offers a chance to honour and promote Ha Giang tea products to domestic and international visitors.
