The Street Fair is grandest show of the year for the Bais. Held from the 15th day to the 21st day of the third lunar month every year at the foot of the Mount Diancang Shan, west to the ancient city of Dali, the Bais are holding the festival mainly pray for a good harvest.
Legend has it that the third princess of Dali fell in love with a young fisherman. On the 15th of the third lunar month, the two went to the moon to buy fishing net and other working instruments but returned home empty-handed. The local people somehow managed to relocate the trade fair to the earth and then the trade began in Dali. Until now, the Bais still call the Third Month Street the “Moon Street.”
The traditional commodities traded at the fair are horses, mules, tea, medicines etc. But now, both the trading place and the commodities have changed a lot. In addition to the exchange of commodities, there are horse racing, performance of operas, folk singing and dancing, attracting tens of thousands of visitors, including those from other Chinese ethnic groups as well as tourists from over ten countries and regions. Moreover, the Third Month Street Fair is also an occasion for love.
