Yi Peng, or the "Festival of the Second Month," is one of the oldest traditions in Lanna culture, dating back to the 14th-century Buddhist era. The word "Yi" refers to the second, while "Peng" refers to the full moon. On this special day, the Lanna people perform ceremonies to honor their ancestors and pay worship to the Triple Gem (Buddha, Dhamma, and Sangha) by floating Sapaos, releasing Krathongs, and lighting lanterns in reverence for light.
A long-standing legend speaks of the floating Sapaos, which originated in the Kingdom of Hariphunchai. The story goes that the people of the city were forced to flee a deadly plague to Hongsawadi city, and after the illness subsided, they returned home. To memorialize their loved ones who were separated on the way back home, they floated Sapaos down the river in remembrance. Another tale tells of lighting lanterns to worship the Buddha, inspired by Siyama Devaputra who transformed into a bird and flew around the Buddha with a lantern, resulting in the entire continent shining brightly. The people who saw this miracle adopted the tale of the practice of lighting lanterns to worship the Triple Gem during the Yi Peng festival since then.
In the upcoming "Yi Peng Chiang Mai 2024," the event will be held under the theme "Lanna, Worship and Light," from November 14 to 17, 2024. The city of Chiang Mai will be illuminated with several lights creating an atmosphere of faith and hope, shining brightly in every corner of the city. This event will bring blessings and beauty to all visitors, offering an unforgettable experience. This year will be especially meaningful as Chiang Mai recovers from the devastating floods of 2024. This is our chance to come together to help restore the city.
Visiting during this festival not only offers a chance to enjoy the beautiful Lanna traditions but also contributes to the economic revival and supports local communities.
