Yi Peng Festival is my favorite festival. Yi Peng Festival coincide with Loi Krathong Festival which is celebrated in North of Thailand. People usually make Khom Loi ,a multitude of Lanna-style sky lanterns are launched into the air by through the sky.
On the night of the full moon, Thais launch their krathong on a river, canal or a pond, making a wish as they do so.
