Seup Chada is a ritual blessing for longevity. Merit and blessings are accrued by the participants via cotton strings as monks chant. Wat Chiang Man (Chiang Mun) was built in 1297 CE and is thought to be Chiang Mai's oldest temple. It was built on the spot which had been used by King Mangrai as a camp during the construction of his new capital city Chiang Mai. Chiang Mai (meaning 'new city'), sometimes written as 'Chiengmai' or 'Chiangmai', is the largest and most culturally significant city in northern Thailand. King Mengrai founded the city of Chiang Mai in 1296, and it succeeded Chiang Rai as capital of the Lanna kingdom.
