Pác Bó
Pác Bó is a small village in Cao Bằng province, northern Vietnam, 3 km from the Chinese border.
Near this village is a cave, Hang Cốc Bó (today often called Hang Pác Bó) in which Hồ Chí Minh lived for seven weeks, during February and March 1941, when he returned after 30 years of exile. Consequently, it is now a tourist site.
