Ho Chi Minh City (Saigon) is the business and financial hub of Vietnam. As well, it is a popular tourist destination due to its fascinating culture, classic French architecture, and sleek skyscrapers as well as ornate temples and pagodas.Located some 60 kilometers to the northwest of Ho Chi Minh City, the Cu Chi tunnel network is an extensive labyrinth of underground tunnels stretching all the way to the Cambodian border. Back then, the tunnels were a means of communication between villages and they also helped the Vietnamese evade French soldiers scouting the area.
