Khong Chai district

Mueang Fa Daet Song Yang (Thai: เมืองฟ้าแดดสงยาง) is the site of a prehistoric community surrounded by earthen mounds about five kilometres long.

[3] The district is the site of some of Thailand's largest e-waste recycling businesses.

Absent any local disposal facilities, the scrap is trucked to incinerators in Sa Kaeo and Saraburi.

[4] The district is divided into five sub-districts (tambons), which are further subdivided into 48 villages (mubans).

There are no municipal (thesaban) areas, and five tambon administrative organizations (TAO).
