It is possible for ordinary backpackers to travel all over Vietnam from north to south in eight days. If you don't like rushing, I suggest only going to the south. Briefly describe the cities or regions in Vietnam from north to south as follows: Hanoi: old street, socialist style city, Ho Chi Minh memorial hall, water puppet show, snacks Sabah: terraced fields, alpine ethnic groups (similar to Guangxi Longsheng) Halong Bay: karst landform in the sea. Village (not as good as Guilin) Hue: Ancient Imperial City Da Nang: Landing place of American troops in Vietnam War, coastal highway (bicycle) Hoi An: ancient town, traditional culture, bar, food, Lijiang River in Vietnam, Meishan (Champa relic) Nha Trang: coastal city, sea fishing, mud bath Mina: traditional fishing village, holiday house, surfing. Unification Palace Xining: the birthplace of Gao Tai (polytheism created by Vietnamese, with Sun Yat-sen as one of the main gods) Guzhi: the remains of tunnel warfare in Mekong Delta (Meituo, Qinyou and Toutong): traditional fishing village Fuguo Island: the best beach in Vietnam, with few tourists.
