Last weekend, Viettel High Technology Industries Corporation (VHT) donated 2 bookshelves with 100 STEM books to two mountainous schools, Chieu Yen Primary School and Chan Son Secondary School, in Yen Son district, Tuyen Quang province.

These activities are part of the annual "Gratitude" series organized by VHT. They are meant to honor the generations who sacrificed for the cause of national defense, while also contributing to the expression of the moral principle "When drinking water, remember its source," spreading the good traditional values within the community.
