Dhutanga (Known in Thai as 'Thudong') is a group of thirteen austerities, or ascetic practices, most commonly observed by Forest Monastics of the Theravada Tradition of Buddhism.

All Forest Monks will observe at least one of the dhutanga austerities. The dhutanga austerities are meant to deepen the practice of meditation and assist in living the Holy Life. Their aim is to help the practitioner to develop detachment with material things including the body.

King Mengrai founded the city of Chiang Mai (meaning 'new city') in 1296, and it succeeded Chiang Rai as capital of the Lanna kingdom. Chiang Mai sometimes written as 'Chiengmai' or 'Chiangmai', is the largest and most culturally significant city in northern Thailand.
