The '100-year old market' was founded by a community of Chinese immigrants. His name 'Khlong 12 Hok Wa' corresponds to its location: at the junction of the 12th canal and the 'Hok Wa' south canal in the Rangsit Canal. Over time, this market becomes one of the largest and most prosperous due to its critical location for transportation and military use. At a time of the construction of the canals, relentless power struggles between the newcomers prompts the community to convert to catholicism, to receive protection and access to better health care and education.
