"Ulaanbaatar Grassland Night" is a Mongolian-style new century pure music work, without lyrics, collected by the composer Li Zhihui's "Our Gone Home 2" music album. The soulful performance of the Morin Fhuur, the original Humai, and the long notes of the natural female voice are perfectly integrated. After listening to it, I was deeply moved and deeply immersed in it.
