Despite religion being closely-monitored by the Vietnamese government, a unique form of Buddhism is practiced by a large chunk of the population. On May 17th, millions turn out at lavishly-decorated temples all across the country to celebrate Buddha’s birth (and enlightenment, which legend says was achieved on his birthday) by taking part in parades, games, and sermons, and by spending time with friends and family. You’ll likely need a facemask to avoid all the incense smoke drifting around at times, but it just adds to the atmosphere of this solemn and important celebration.
