The Thai greeting referred to as the wai (Thai: ไหว้, pronounced [wâːj]) consists of a slight bow, with the palms pressed together in a prayer-like fashion. It is very similar to the Indian Añjali Mudrā/namasté and the Cambodian sampeah. The higher the hands are held in relation to the face and the lower the bow, the more respect or reverence the giver of the wai is showing.
The wai is also common as a way to thank someone or apologise.
The word often spoken with the wai as a greeting or farewell is sawatdee (สวัสดี, pronounced [sàwàtdiː]). This word was coined in the mid-1930s by Phraya Upakit Silapasan of Chulalongkorn University. This word, derived from the Sanskrit svasti (meaning "well-being"), had previously
been used in Thai only as a formulaic opening to inscriptions. The strongly nationalist government of Plaek Pibulsonggram in the early 1940s promoted the use of the word sawatdee amongst the government bureaucracy as well as the wider populace as part of a wider set of cultural edicts to modernise Thailand.

Most people live densely along both sides of the canal from one end of the canal to another.The majority of this people are agriculturists. They grow several different kinds of fruit and vegetable for examples oranges, grapes, papayas, cabbages, bean, onion and etc. The land in this area is naturally fertile. Apart from providing transportation, Damnoensaduak Canal also provides farmers with adequate water for agricultural purposes for the whole year around.

Moreover; these small canals also become protitiouus ways of taking their agricultural products to the markets in neighbouring provinces and Bangkok.
