Sieng Kong or sometimes spell Xiang Gong and Siang Kong (Thai: เซียงกง, pronounced [sīe̞ŋ kōŋ]; Chinese: 仙公; pinyin: Xiān gōng) is a neighbourhood in the area of Bangkok's Chinatown, Talat Noi sub-district, Samphanthawong district.
It is well known to most Thais as the car part and secondhand engine machine center.
[1] It covers the area from Talat Noi, Song Wat to parts of Khao Lam, Tri Mit and Charoen Krung roads.
Its name "Sieng Gong" came from a small joss house called Sieng Gong, which settle on Song Wat close to Charoen Krung roads and present-day Odeon Circle.
The old joss house was established in 1854 (corresponding to the 4th year of Xianfeng Emperor's reign of Qing dynasty) by a group of Hoklo which settle down around there.
