Phuc An Commune, located in Yen Binh District of Yen Bai Province, is home to the long-established community of Dao Quan Trang (white-trousered Dao) ethnic minority group. Amid the rhythms of modern life, the white-trousered Dao people have preserved values deeply rooted in their ethnic identity—most notably, their traditional clothing and the craft of weaving shrimp traps—both reflecting a lifestyle intimately connected with nature around Thac Ba Lake.
