Far from their Dali homeland, the Bai of Yinyuan have preserved a distinctive costume and a particular dish: Migan, flat rice noodles, eaten like Mixian. In April, they celebrate the Migan Festival.
The festival is most likely been held on a weekend day close to the date given here with activities going on in both Yinyuan and Anding, a nearby Bai village which is actually more interesting than Yinyuan (all modern township).
According to http://www.dongnanyanet.com/Html/?711.html the festival is held in different villages over the period of a week: 浦十七日、安定十八日、因远二十一日, but this does not seem true.
In 2011, the festival started around 10am in the morning and stretched into the afternoon with some dances scheduled for the evening.
