Yisan

Yisan (ยี่สาร, ) is a tambon (sub-district) of Amphawa District, Samut Songkhram Province, central Thailand.

History
Its name "ํYisan" after the hill named Yisan, a local stand out limestone hill as well as canal Khlong Yisan, that runs through the area. Khlong Yisan can be regarded as both a natural canal and a man-made canal. In the part of the man-made canal believed to have been dug at the late of King Mongkut (Rama IV)'s reign. It flows from here to the Gulf of Thailand, which is about 5–6 km (3.11–3.73 mi) away.

The word Yisan presumably derived from "Pasan" (ปสาน) which distorted from the word "Bazaar" in Persian, which means marketplace. Because Yisan has been a center of commerce since ancient times and was a junk boat stop. While some academic believe that the word Yisan is likely to come from Chinese "一 山" (pinyin: Yī shān), which means "one hill".

Yisan's history is older than other areas of Samut Songkhram. Yisan community dates back to the Ayutthaya period there are many excavations of ancient pottery found. Its name appears in the records of two foreigners since the early Rattanakosin period, namely Jean-Baptiste Pallegoix a French cleric which he spelled the name of Yisan as Isan, and Scottish's John Crawfurd.

There is a folk tale telling about the three Chinese brothers who sailed to Siam (now Thailand). But the junk had sunk before reaching the shore, the three brothers then swim, scattered in different directions and separated to live in different places. The oldest brother went to live in the Khao Takhrao, Ban Laem District and last brother went to live in Khao Iko, Khao Yoi District, Phetchaburi Province. While the middle brother went to live in Yisan and became Phophu Si Racha, a sacred Buddha image at Wat Khao Yisan in present day.

Previously, Yisan residents does not contain fresh water for consumption, because the water source of this area is brackish water. Therefore causing locals to have a career that is different from the normal is to row a boat to pump fresh water from other areas such as Khao Takhrao, Bang Tabun in Phetchaburi Province. This occupation was called "lom nam" (ล่มน้ำ). Like other traditional professions, this occupation is about to disappear because of the replacement of tap water.
