"Manlang" is a word in Dai language, which means "beauty". Dai people live in the southernmost part of China, between mountains and basins where mountains and rivers crisscross. The natural environment here is very beautiful and picturesque. Dai people's health-keeping methods are also different, and they attach importance to natural and harmonious humanistic care in their daily lives. The word Manlang is such a perfect combination of natural beauty and humanistic harmony.

"Manlang" is not only the praise of the Dai people for the natural environment, but also can be used to describe the appearance of a person or an object, meaning "beautiful and charming". Just as the ancestors cherished the natural beauty, the aesthetic view of the Dai people is also reflected in the worship of beauty. Through careful decoration and centuries of cultural precipitation, they are integrated with the surrounding environment, reflecting the Dai people's attitude towards beauty.

The word "Manlang" is also constructed to include the words "Man Mei" and "Lang Lang", which has a more detailed meaning. Man Mei refers to beautiful appearance, while Lang Lang is used to describe a person's inner brightness and clarity. The Dai people believe in festivals such as the Water-splashing Festival, which is not only a cultural activity, but also a kind of gratitude and praise for the natural environment, and a kind of care and reward for the feelings between people, which closely links the connotation of the word "Manlang" with the spiritual concept of the Dai people.
