Is there any festival in May of the solar calendar of the Miao people

This is a traditional festival of water rowing competition among the Miao people, which is popular on both sides of the Qingshui River at the junction of Taijiang and Shibing counties in Guizhou, and on both sides of the Bala River of the Taijiang River that feeds into this section of the river, which is known as "ha yang yong" (qab niangx vongx) in the Miao language of Qiandong. Here in Pingzhai, Liao Dong and other sixty or seventy Miao villages, each family has one to two rowing competitions with the dragon boat. Every year on the fifth day of the fifth month of the lunar calendar, or the twenty-fourth to twenty-seventh of these five days, living on both sides of the river, the Miao people take turns to hold a grand and grand dragon boat race.
