There are also Guizhou Tujia's "Wang Niu Mountain Song", the Dong's "Ga August", and the Zhuang's "Zhuang Family Sisters", etc.
Other songs I know of include "Playing a Mountain Song across the Heng Pai", "Maidu Mountain Song", "Pairing the Birds", "When Will the Locust Flowers Blossom", "Maran Mountain Song", "Mountain Songs for Springtime in the Year of the Mountain Songs", "Mountain Songs for the Marriage of the Mountain Songs" and "Unforgettable Streams". Mountain Song Singing in Spring Year by Year", "Mountain Song Marriage", and "Unforgettable Stream".
All of the above are original mountain songs. There are also some such as "Mountain Song is Better than Spring River Water", the theme song of "Liu Sanjie", which was adapted later.
