Nguyễn Hữu Cảnh was born in Lệ Thủy District in Quảng Bình Province, Bắc Trung Bộ, Vietnam (then part of Đàng Trong). In 1698, Canh was sent by Nguyễn Phúc Chu to the south. He founded Gia Dinh garrison there. He called on people from many places in Central Vietnam to settle in these regions. He ordered the building of roads, canals, markets. Saigon has turned into a busy port city since then.
