I want to ask which country Saigon is in.

Vietnam, now known as Ho Chi Minh City.

Ho Chi Minh City is located in the Mekong Delta. At first, it was just a small fishing village called "Poullien Brothers", full of swamps. Khmer people have lived here for centuries, and this place has gradually developed into an important trading port in Zhenla. Because of the dense water network, this area is also called "water wax".

1623, King Cuichita II of Cambodia allowed Vietnamese refugees to enter Preen to escape the civil war between South Ruan and North Zheng of Vietnam, and at the same time built more houses for them to live in. However, the weak kingdom of Cambodia could not cope with the influx of refugees, and Poullien gradually became a part of Vietnamese territory and began to be called "Saigon".

The topography of Ho Chi Minh City

Ho Chi Minh City belongs to the transitional zone between the southeast and the Mekong Delta. There are three types of terrain. The higher terrain is located in Tongchi in the northeast and north, Shoudehe District in the northeast, and a part of the northwest.

The terrain is curved, with an average height of 10-25m. The highest point of Longping Mountain in Area 9 is 32 meters. The depression is located in the southwest and southeast of the south, and the height of this area is within the range of 0.5-2 meters. The medium-height terrain is located in the central city, including most of the old residential areas, parts of the second district and Shoude County. The height of this area is 5- 10 meter.
