Wild means reading Y ǐ and ancient sounds. Only in this way can it rhyme, but now some ancient sounds are not so strict, and middle school Chinese textbooks and reading materials are basically changed to reading yě.
There are many folk poems that have not been recorded in writing for hundreds of years, all of which are sung by artists through memory, so there are often wrong voices. Chi Lechuan's songs are also very similar. In this sense, Yegu should be the voice of "Y m:", which gradually changed in the process of singing and now spread into two voices.
Appreciation of Chilean songs
Chile Song is a northern folk song that spread in the north of the Yellow River during the Southern and Northern Dynasties. Folk songs sing the magnificent and rich scenery of the grassland in the north, and express the pride of the Chilean people who love their hometown and life. The first two sentences show that Chilechuan is located at the foot of the towering Yinshan Mountain, which sets off the grassland background very magnificently.
The next two sentences, using the metaphor of "vault", say that the sky is like a yurt, covering all directions of the grassland, so as to describe the magnificent scene of the distant future and the connection between Amano and Amano. The last three sentences describe the panoramic view of the grassland with rich water plants and fat cattle and sheep. There is stillness, movement, image and color.
