Hong Saeng (th|ห้องแซง, pronounced as /th/) is a tambon (subdistrict) of Loeng Nok Tha District, Yasothon Province, Isan region (northeastern Thailand). In 2018 it had a total population of 11,485 people.[1]
Hong Saeng is a long time and secured home of Phu Thai ethnic group. Their ancestors emigrated from the Xépôn in Laos since 1849–1850, and before that.
Originally, the area was called "Dong Pa Hong Ya Saeng" (ดงป่าฮ่องหญ้าแซง) and was distorted to be "Hong Saeng" in the present day.
Hong Saeng considered as an area near the border of three provinces, namely Yasothon, Roi Et, and Amnat Charoen, most of the area consisting of lowlands from central to western parts.
Neighboring tambons are (from the north clockwise): Kut Chiang Mi, Samakkhi, Si Kaeo, and Pha Nam Yoi of Nong Phok District, Roi Et Province.
Most Hong Saeng residents work in agriculture.
The tambon is subdivided into 19 administrative villages (muban).
