Sangjieben was born in 1966 in Wutun Village, Tongren County, Qinghai Province, known as the hometown of Regong art. At the age of 8, he studied under Master Jiancuo, who is known as one of the "Four Heavenly Kings" in the Regong region, immersing himself in the theoretical knowledge and practical skills of traditional Tibetan Buddhist painting, as well as three-dimensional clay sculpture and carving techniques.

In 1974, he studied traditional Tibetan Buddhist painting techniques under the guidance of Master Jianmu Cuo from Wutun Village in Tongren County. In 1980, he formally became a disciple and systematically learned the craftsmanship of Thangka painting and clay sculpture carving. He has painted over a hundred Thangka and murals in Buddhist holy sites such as Longwu Temple in Qinghai, Labrang Monastery in Gansu, Potala Palace in Xizang, and Wendu Monastery, the former residence of the Panchen Lama.

In 1982, the 10th Panchen Lama visited the hometown of Regong art and had a cordial conversation with Master Jianmu Cuo. He encouraged the preservation and inheritance of the Tibetan Thangka culture.

In 1991, upon the invitation of the Kumbum Monastery Management Committee and the Ajia Living Buddha, he collaborated with Chinese arts and crafts master Xia Wucai Lang and others to paint murals at Kumbum Monastery and restored 36 murals inside the temple (Xiaojinwa Temple), a project that lasted for three years. These murals are still well-preserved at Kumbum Monastery and are available for visitors to admire.

In 1994, a Thangka exhibition was held at the National Cultural Palace, opening the door for the external exchange of Regong art.

From September 1995 to August 1996, I pursued further studies in the field of arts and crafts theory at the Beijing Academy of Fine Arts, at my own expense.

In 2007, he was appraised as a National First-Class Technician and an Expert in National Vocational Skill Certification and Examination by the Ministry of Human Resources and Social Security of the People's Republic of China.

Since 2008, he has been dedicated to the education and teaching of Regong art inheritance, establishing the first Huangnan Regong Art Vocational Training School. The school offers majors such as Thangka painting, pile embroidery, and sculpture making, and has successfully trained over 2,000 students.

In 2008, he was awarded the title of "National Excellent Migrant Worker" by the State Council.

In 2010, he was awarded the title of "Folk Craft Master of Qinghai Province" by the Qinghai Provincial Department of Culture, Press and Publication, the Provincial Department of Human Resources and Social Security, the Development and Reform Commission, and other relevant departments.
