Monyu, also called "Highland Jiangnan (the Southern Valley of the Changjiang River)", is picturesque with evergreens in all seasons. It has attracted worldwide attention because Dalai the sixth Cangyangjiaco, a great romantic poet was brought up here. A Collection of Love Songs by Cangyangjiaco, now translated into many languages, is said to have been born out of Moinba folksongs. His works have kept many of the meters and styles of the Moinba love songs. In this area, men and women are free to make friends with each other, and love songs have naturally become a link between young hearts. They have composed countless love songs all through the centuries.

Love and marriage between Moinbas are quite free, too. They marry on the basis of true love and their marriages are generally not affected by wealth or rank. An ancient custom, "uncle on the mother's side raising hell on the wedding," is still in existence as part of their folkway, though no uncles today stand in the way of their nieces' marriages. The uncle, putting on a peremptory yet humorous show, actually adds even more fun to the wedding ceremony.
