Thai People and Culture

People
Thailand's people are largely Thais, although there are significant minorities of Chinese and assimilated Thai-Chinese throughout the country, Muslims in the south near the Malaysian border and hill tribes such as the Karen and the Hmong in the north of the country. The overwhelmingly dominant religion (95%) is Theravada Buddhism, although Confucianism, Islam, Christianity and animist faiths also jostle for position.
The people respects the royalty, the King and the Queen, very much. Even pointing fingers to the picture of them is considered bad.

Culture

Mainland Thai culture is heavily influenced by Buddhism. However, unlike the Buddhist countries of East Asia, Thailand's Buddhists follow the Therevada school, which is arguably closer to its Indian roots and places a heavier emphasis on monasticism. Thai temples known as wats, resplendent with gold and easily identifiable thanks to their ornate, multicolored, pointy roofs are ubiquitous and becoming an orange-robed monk for a short period, typically the three-month rainy season, is a common rite of passage for young Thai boys and men.

One pre-Buddhist tradition that still survives is the spirit house (ศาลพระภูมิ saan phraphuum), usually found at the corner of any house or business, which houses spirits so they don't enter the house and cause trouble. The grander the building, the larger the spirit house, and buildings placed in particularly unlucky spots may have very large ones. Perhaps the most famous spirit house in Thailand is the Erawan Shrine in central Bangkok, which protects the Erawan Hotel (now the Grand Hyatt Erawan) - built in 1956 on a former execution ground - and is now one of the busiest and most popular shrines in the city.

Some traditional arts popular in Thailand include traditional Thai dancing and music, based on religious rituals and court entertainment. Famously brutal Thai boxing (muay Thai), derived from the military training of Thai warriors, is undoubtedly the country's best known indigenous sport.
In addition to the mainland Thai culture, there are many other cultures in Thailand including those of the "hill tribes" in the northern mountainous regions of Thailand (e.g., Hmong, Karen, Lisu, Lahu, Akha), the southern Muslims, and indigenous island peoples of the Andaman Sea.
