The Yi people in Ejia town of Yunnan province, who are still singles, will head to the streets for Breast-Touching Festival (Monai Jie) on the 14th, 15th and 16th days of the month.On these days, the men are welcome to touch the women's breasts.
Legend has it that the festival began around the Sui Dynasty (AD 581 – 619) when most of the teenagers of the Yi tribe were forced into the army and died in wars.
The people then carried out prayers to commemorate the dead, and it happened that the ceremony was held in the seventh month.
According to the wizards, the dead were unrest because they had not touched a woman before.
And so, they wanted 10 "pure and untouched" ladies to accompany them in the afterworld.
In a move to prevent them from being chosen, the single women – aged 15 and above - then asked the men to touch their breasts, and the custom is past down for generations.

Whether it's true or not this ritual can calm down the dead, i don't believe it at akk as it's doesn't have scientific bases at all. I doubt this custom will be pass down for another thousand year as when the young women are now more educated than they were in last centuries (in China) . As they become open-minded, they will not participate at this custom as it' doesn't benefit them at all.
