Nowadays, Chaina influence in many area. If you go aboard you will notice that there are some ares of Chiness people or Chiness community. We called "Chaina Town". In Thailand we know as "Yaowarat". Yaowarat is the area of Chiness community and also there are a lot of Chainess culture happen there.
Chinatown is a colourful, exotic and busy area, packed with market stalls and probably the greatest concentration of gold shops in the city. The Chinese community still continue their own traditions and religious practices, and the area is quite unlike the rest of Bangkok.
However, the Chinese community in Bangkok, descendants of early traders, have been living in Thailand for generations, and generally consider themselves very much as Thais; most can no longer speak any Chinese. The area has a somewhat seedy historical reputation for large numbers of opium dens, brothels, pawnshops and a fondness for gambling that used to prevail.
Today, gold shops and pawnshops are still very popular in Chinatown, and can be found almost anywhere and everywhere. Drug dealing, prostitution and gambling (all now illegal in Thailand) are also still thought to be widespread in this area - although they are not likely to be very noticeable to the average visitor. So don't expect to see any go-go bars in Chinatown!
