Tuyên Quang Province in the context of "Kam people"

Guangxi, officially the Guangxi Zhuang Autonomous Region, is an autonomous region of the People's Republic of China, located in South China and bordering Vietnam (Tuyên Quang, Cao Bằng, Lạng Sơn, and Quảng Ninh Provinces) and the Gulf of Tonkin. Formerly a province, Guangxi became an autonomous region in 1958. Its current capital is Nanning.

Guangxi's location, in mountainous terrain in the far south of China, has placed it on the frontier of Chinese civilization throughout much of Chinese history. The current name "Guang" means "expanse" and has been associated with the region since the creation of Guang Prefecture in 226 AD. It was given provincial level status during the Yuan dynasty, but even into the 20th century, it was considered an open, wild territory. The abbreviation of the region (Chinese: 桂; Hanyu pinyin: Guì; Zhuang: Gvei) comes from the name of the city of Guilin, the provincial capital during both the Ming and Qing dynasties.

Tuyên Quang (listen) is a city in Vietnam, and is the capital of Tuyên Quang Province.

Cao Bằng is a province of the Northeast region of Vietnam. The province has borders with Hà Giang, Tuyên Quang, Bắc Kạn, and Lạng Sơn provinces within Vietnam. It also has a common international border with Guangxi province in China. The province covers 6,700.39 km (2,587.04 mi) and, as of 2023, its population was 547,849 people.

The area has a rich history tracing to the Bronze Age Tây Âu (西甌) Kingdom of the ethnic Tày. Cao Bằng has several points of historical interest as well as many natural features such as the Pác Bó (at the mouth of the confluence of two rivers, the Bằng Giang and Hien rivers) where Hồ Chí Minh in January 1941 established a revolutionary force at Cốc Bó cave, the Mạc emperor's Temple, the Kỳ Sầm Temple, Coi Bin Church, the Bản Giốc waterfall area at the international border between Vietnam and China, and the Thang Hen Mountain Lake.
