Before the 15th century, this territory was almost not under the control of any country in reality, but its was ruled by many chiefs (p'tao, phìa tạo), who had received some favors from Annamese and Chinese emperors.

At the beginning of the 16th century, when the political situation in the central area of An Nam had many fluctuations, Đại Man once again became a fighting place between the two forces Lê-Trịnh and Mạc.

When the Government of the Democratic Republic of Vietnam was established in January 1946, the regime of "châu" (canton) and "phủ" (prefecture) was abolished to be replaced by "huyện" (rural district) and "tỉnh" (province).

On January 25, 2006, the Government of Vietnam issued Decree 14/2006/NĐ-CP[note 5] to re-arrange the boundaries of communes in Tuyên Quang province.

Therefore, the largest resource of the rural district is forest and limestone mountains, which has almost been banned from exploiting since the 2000s to become an ecological conservation area.

However, due to the intense impact of stressful political situation, some have chosen solutions to return to Guangxi, Guangdong or refugeed in Hong Kong with the implicit agreement of local authorities of Tuyên Quang.

The remaining people have accepted to register as part of other ethnic groups (Kinh, Tày, Nùng, Yao...) to have the opportunity to continue studying and working.

So far, the Hoa in Na Hang consists of only a few small clans settling in the North of the rural district, where the terrain is relatively dangerous.

Due to the specificity that the locality has the process of forming and developing customs for a very long time, so early, Na Hang has become an object of exploitation of literature and then cinema.

[3] Some works have used it as the context : Na Hang is known as the sticky rice (nếp nương) supplier and products originating from forest in large quantities of the entire mountainous region of the Northern Vietnam.
