Chinese mediums will perform mortification of the flesh to exhibit the power of the Deities, and the rites and rituals seen are devoted to the veneration of various Deities. Such idiosyncratic traditions were developed during the 19th century in Phuket by the local Chinese with influences from Thai culture. In the north, there is a small minority of Chinese Muslims known as Chin Ho. They are mainly the descendants of Hui people migrated from Yunnan, China. There are seven Chinese mosques in Chiang Mai. The best known is the Ban Ho Mosque. Dialect groups The vast majority of Thai Chinese belong to various southern Chinese dialect groups. Of these, 56 percent are Teochew (also commonly spelled as Teochiu), 18 percent Hakka and 11 percent Hainanese. The Cantonese, Fuzhounese, Henghua and Hokkien each constitute eight percent of the Chinese population and three percent belong to other Chinese dialect groups. A large number of Thai Chinese are the descendants of intermarriages between Chinese immigrants and Thais, while there are others who are of predominantly or solely of Chinese descent. People who are of mainly Chinese descent are descendants of immigrants who relocated to Thailand as well as other parts of Nanyang (the Chinese term for Southeast Asia used at the time) in the early to mid-20th century due to famine and civil war in the southern Chinese provinces of Guangdong (Teochew, Cantonese and Hakka groups), Hainan (Hainanese), Guangxi (Cantonese group) and Fujian (Hokkien, Hockchew and Henghua groups). Teochew Traditionally, the Teochews comprise a majority population of coastal provinces like Bangkok, Chonburi and Chachoengsao until the 1950s, in which later it was overwhelmed by Central Thai internal immigrants. Many of Thai military commanders as well as politicians come from Teochew backgrounds, while others were involved in trade. During the reign of King Taksin, some influential Teochew traders were granted certain privileges. These prominent traders were called "royal Chinese" (Jin-luang or จีนหลวง in Thai). Hakka Hakkas are mainly concentrated in Chiang Mai, Phuket and central western provinces. The Hakka own many private banks in Thailand, notably Kasikorn Bank and Kiatnakin Bank.

This group are not very prominent and are mainly concentrated in Bangkok and the central provinces. Although Cantonese from Yulin primarily live in Betong of Yala Province
