Mr. Yu Daoquan's Chinese version of "The Sixth Dalai Lama Cangyang Gyatso" 1930 is the best (version name: published by the Institute of History and Language of Academia Sinica, No.5).
Since then, Liu Jiaju's edition 1932, Zeng Biwen's edition 1939, and Liu Xiwu's edition have interacted with each other and can also be used as a "polished edition".
But now there are very few original ones. If necessary, you can refer to the later translation of love song Yu Daoquan (English version 1930), which is also the real version, and other translations are not the original version.

Relevant evaluation of Cangyang Jiacuo:
The eminent monk of Tibetan Buddhism commented on him: Vader, by virtue of secular law, made the common people see a broad spiritual world in the birth law, and his poems and songs purified the hearts of generations. With his most sincere compassion, he made the people feel that Buddhism was not out of reach, and his maverick gave us real education.
Du Qi's History of Tibet in the Middle Ages: The young Cangyang Jiacuo became a victim in some incidents, but his ending was a prophecy displayed by the guardian gods, all of which made people forgive his weakness. Now people generally like him again, and his strange behavior is interpreted as a vague and obscure behavior of God.
Zhang Songcao: Cangyang Jiacuo is the god who was created, but his rebellion denied the creation movement itself.
Rong, a professor of literature at Nankai University: Cangyang Jiacuo is the most outstanding poet in the history of Tibetan literature. His poems have been told by families in Tibetan areas for more than 300 years, and are deeply rooted in people's hearts and household names.
Li Xueqin: Cangyang Jiacuo used this meter to write the love songs of Cangyang Jiacuo, a moxibustion population, which promoted the vigorous development of' He' style love songs, making it a poetic meter with great influence and wide spread among Tibetan love songs, competing with many' Lu' style love songs.
