There is a famous "Nimu Three Musts" in Lhasa, Tibet, which refers to the sculptures of Xila Tibetan paper, Tunba Tibetan incense and Songpu in Nimu County. In Xuela Village, Nimu County, there is a family that has been engaged in Tibetan papermaking for generations. They are Ren Duojie, the non-genetic inheritor of Tibetan papermaking technology, and his two sons, Ge Sang Tenzin and Luo Qiong. This family is a witness to the history of Tibetan paper, and also an innovator to revive the Millennium Tibetan paper in the new era.

The palm, fingers and nails of the papermaker were stained by the root of Stellera chamaejasme, and the fingers were obviously swollen.

Luo Qiong used a wooden stick to stir the pulp in a special jar. Pour the pulp into the net rack and shake it at a uniform speed, and the pulp becomes even and thin. Air-dry the pulp on the screen frame, and take down the finished Tibetan paper. .

The process of hiding paper is complicated, and almost all the processes need to be made by hand. Tibetan paper is neither rotten nor moth-eaten, because the raw material it uses is the root of the local plant Euphorbia fischeriana in Nimu. This plant is distributed on high-altitude slopes in Tibet, and cattle and sheep never eat it because its roots are slightly poisonous. Even its flowers have an unpleasant smell, which makes people dizzy for a long time.

In Tibet, many ancient scriptures are written in this Tibetan paper, which can be preserved for hundreds or even thousands of years.

The raw material of Tibetan paper is taken from a thin inner membrane under the epidermis of Stellera chamaejasme root, which needs to be torn off manually. Peeling is the most complicated process of Tibetan paper, and because the skin is toxic, it will be corroded when it comes into contact with human hands for a long time, so that it will swell and turn white.

Blanch the peeled plant skin with boiling water, then smash it with stones, and add water to make a slurry; After that, the paper pulp is evenly poured into the paper-making mesh frame and shaken evenly in the pool to form a film; After drying, it is hidden paper.

These processes are simple to say, but in fact, each process needs practice to make perfect. Tsering Dorje made Tibetan paper with his father when he was 0/4 years old. He persisted for more than 50 years and spared no effort to protect and inherit this craft. In 2006, Tibetan paper production technology was included in the first batch of national intangible cultural heritage list. In 2009, it was awarded the title of representative inheritor of national intangible cultural heritage by the Ministry of Culture.
