In Ho Chi Minh City, Vietnam, I prefer to call its original name Saigon. The name Saigon may be more suitable for the current city of Ho Chi Minh, which is said to be the most fashionable metropolis in Vietnam. Most of the foreign backpacks that come here live in the gathering place of the backpackers of Fan Laowu Street. Day and night are like flowers and wine. The most attractive tourist attraction in Ho Chi Minh City is the two old buildings in the city. First, the Cathedral of the Virgin, commonly known as the Red Church, was left behind during the French colonial period. Therefore, it is also a precious cultural relic building. Second, the central post office on the left side of the Cathedral of Our Lady, on the east side of the Red Church, was designed by French architects at the end of the 19th century. As a post office, it is simply too beautiful. It looks like an old station in Europe, very cool. The hall is decorated with ornate, parquet tiles and a semi-circular high dome, which is very classical and very atmospheric.
