Trong Con Sub-zone, located on the left bank of the Lo river in Tuyen Quang, is regarded as a sacred symbol of Vietnam’s revolutionary history. It witnessed the first footsteps of the Vietnam Propaganda Unit of the Liberation Army and played a vital role in the early development of the Vietnamese revolution. Nearly eight decades after serving as a resilient revolutionary base, the sacred land of Trong Con Sub-region is now experiencing a daily transformation.

In modern life, Gio cake of the Tay people in Tuyen Quang has retained its traditional flavor, much like the way they have preserved their cultural identity.
