Tunmi Sangbuza is a great linguist, translator, the first master of Buddhist communication and the enlightener of Songzan Ganbu in the early Tibetan society. His name, together with his immortal achievements, will be forever recorded in history and admired by future generations.

In the 7th century, Tunmi Sangbuza was born in the Tunmi family in Tunbaigou (today's Nimu County) on the upper reaches of the Yarlung Zangbo River. His father, Tunmi Aru, was not only an eminent monk of Ben religion, but also a former Minister of Zampson Ganbu of Tubo. Her mother's name is Aqiu.

Tunmi Sanbuza is smart and intelligent. At the age of thirteen, he was recalled to the palace by Songzangganbu, and was officially appointed minister by Songzangganbu the following year. Sixteen bright and handsome young people, including Tunmi Sanbuza, were sent to India to study Sanskrit and Jurassic.

"Tunmi and others passed through the territory of Nybra (near Kathmandu, the capital of Nepal). King Mandarin of Benibara lost to King Moha, for which the King gave medicines to relieve summer heat." But Tianzhu's tropical climate has made it difficult for 16 young people who have lived on the cold plateau for a long time to adapt. Most of them died of illness in other places. Only Tunmi Sangbuza learned Sanskrit and language from a Brahmin named Li Jing and a scholar named Razebelsenger. He successfully completed seven years of study, respected Buddhism, studied hard, and achieved excellent results. Therefore, he was honored by Tianzhu people as "Sangbuza" (meaning a good Tibetan, "Tunmi" is his family name).

Tunmi Sangbuza returned to Tubo with his teachers'affection and understanding of Sanskrit. Following Songzan Ganbu's wishes, he created 30 basic letters in Tibetan based on 50 basic letters in Sanskrit and the characteristics of Tibetan language, and four Tibetan vowel letters from 16 vowels in Sanskrit. Tunmi also removed five inversions and five reduplications from the 34 Sanskrit sub-syllables, added vowel-ah characters to the vowels, added six Sanskrit sub-syllables such as Ka, Qi, Jia, Xia, Hu, A (transliteration), and formulated four alphabets and 30 sub-syllables in Tibetan.

According to historical records, after Tunmi created Tibetan, he made Tibetan eulogies to Songzan Ganbu. Zampu was very happy and appreciated them. In order to motivate his subjects to learn Tibetan, Zampu worshipped him as a teacher. In Grandma Zao (now more than ten kilometers east of Dazi County, Lhasa City, Tibet, for the palace of the Tibetan Queen of Songzangganbu), she devoted herself to learning Tibetan and other cultures, not contacting the outside world, and studying in closed doors. Songzan Ganbu respected Tunmi very much. Some ministers thought that he should not be so respected. Tunmi said, "I am the first resident student in the snow area." So the anger subsided, the whole world learnt Tibetan, and the lotus of wisdom blossomed. In Tubo, politicians, militarists and skilled builders such as Gar Dongzan, Gar Qinling and Minister Nian Kusangyangdun appeared. Then, in order to correctly use the Tibetan phonetic system, rules and the empty character "Ge", Tunmi Sanbuza compiled the Thirty Fundamental Songs of Grammar and Grammar according to the declarations of ancient India and the characteristics and methods of his own Tibetan language, which made the Tibetan nation have its own language for the first time. With the emergence of works and translations recorded in Tibetan, Tibetan history has entered a new stage of civilization.

Tunmi Sanbuza is not only a creative researcher in Tibetan language and grammar, but also a translator. At the same time, he personally led Songzan Ganbu's disciples to practice Buddhist Dharma in Pabanka for three years. In accordance with the development of the human environment in Tibet at that time, he wrote "The Thirty Songs and the Turning Wheel" (i.e. the Thirty Fundamental Songs of Grammar), the Law of Character Change, and "The Wind of Tunmi Valley" (i.e. the Gender of Grammar). In addition to eight other linguistic and grammatical works, he has also translated more than 20 Buddhist sutras, such as the Twenty-first Classic of Hidden Confidence, the Treasure Star Dharani Sutra, the Ten Good Sutras, the Prajna 100,000 Songs, the Baoyun Sutra, and the Baomu Sutra. These translated Sutras were included in the Dazang Sutra Ganzhur, and Buddhist classics and cultural works from Tianzhu, Handi, Nibra, Keshimiro, Hetan and other places were translated into Tibetan, and assimilated and merged to form the world-famous Tibetan culture.

Up to now, there are still many relics left over from that time and six-character truth inscribed on huge stones in the Buddhist monk's practice cave and Pabanka temple. Historical records show that this is the relic left by Songzangganbu and Tunmi Sangbuza who studied and practiced together.

Later, Tunmi Sanbuza assisted Songzangganbu in accomplishing the great cause of cultural pluralism and common prosperity in Tibet. He traveled thousands of miles to Nepal, Chang'an (now Xi'an) and other regions to marry Nepalese princesses and cultural princesses, thus speeding up the pace of development of harmonious coexistence between Tibet and its neighboring countries.
