Dia Tren: Inside Cao Bang's Traditional Paper Village

Nestled in a lush, green valley beneath the towering limestone mountains of Quang Uyen district, Dia Tren is a village that quietly guards one of Cao Bang's most profound cultural secrets. Long before you see the traditional houses, you will hear the rhythmic, echoing thud of wooden pestles - a sound that has served as the heartbeat of this Nung An ethnic community for generations.

For international travellers exploring the Northeast loop, Dia Tren is more than just a scenic stop. It is a rare "living heritage village" where the ancient art of making paper by hand is still practiced daily. Far from a staged tourist attraction, this is a place where workspace, daily life, and centuries-old traditions blend seamlessly together.

A vessel for memory and culture
To truly appreciate Dia Tren, one must understand that this paper is not simply a commercial commodity. For the Nung An people, it is a sacred material deeply woven into their spiritual and cultural identity.

In the era before industrialization, this rustic, ivory-coloured paper was the sole medium used to record family genealogies (gia pha), write ancient Nom script, and preserve local poetry. It was, and still is, essential for sacred spiritual rituals and festivals. According to local artisans who have dedicated decades to the craft, every single sheet is a crystallization of community knowledge, beliefs, and ancestral connection.

When you hold a piece of Dia Tren paper, you are not just holding a stationary item; you are holding a physical piece of indigenous memory that has survived the test of time.

The art of "may sla" and mountain water
The creation of Dia Tren paper is a masterclass in patience, relying entirely on the natural elements of the forest. The process is completely devoid of modern machinery or chemical treatments.

It begins with foraging for the "may sla" tree - a local plant renowned for its fibrous bark. Artisans meticulously peel away the dark outer layer, keeping only the soft, white inner bark. This material is mixed with lime and boiled continuously for hours to break down its tough structure. Afterwards, the bark is carried down to the local stream, where it is soaked in the flowing mountain water for half a day to achieve perfect elasticity.

Next comes the most physically demanding stage. The softened bark is placed on a block and pounded with a heavy wooden pestle for nearly an hour. It is back-breaking work that demands immense stamina. Once the fibers are pounded into a fine pulp, they are transferred into a large wooden trough and mixed with water and a natural plant-based glue.

Using a specialized bamboo frame, the papermaker performs a delicate technique known as "seo" - gracefully sweeping the frame through the water to catch a perfectly even, paper-thin layer of pulp. Finally, the wet sheets are peeled off the frame and plastered directly onto the walls of the village houses to dry under the mountain sun.

Breathing new life into an ancient craft
Like many traditional crafts across Asia, the paper-making industry in Dia Tren faced a period of decline. The rise of cheap, mass-produced industrial paper threatened to render this meticulous handmade process obsolete.

However, a shift occurred in 2021 when the Non Nuoc Cao Bang UNESCO Global Geopark recognized the immense cultural value of the village. Dia Tren was officially integrated into the Geopark's Eastern route, aptly named "Experiencing indigenous culture in a wonderland".

The preservation philosophy here is incredibly smart. Rather than forcing the village to mass-produce cheap paper for tourists, the focus is on elevating the value of each individual sheet - much like the revered Washi paper of Japan. By keeping the authentic, handmade process intact, the village has transformed its heritage into a sustainable livelihood, proving that conservation must go hand-in-hand with economic survival.

Hands-on heritage for the modern traveller
Today, Dia Tren welcomes travellers not as passive observers, but as active participants.

Walking through the peaceful dirt roads, visitors are invited to step right into the open workshops. You can try wielding the heavy wooden pestle to crush the bark, learn the delicate balancing act of filtering the pulp through the bamboo frame, and even stamp your own freshly dried paper.

To adapt to the modern traveler, the younger generation of Dia Tren has creatively expanded their craft. You can now purchase beautifully bound notebooks, traditional folding fans, calligraphy art, and decorative gift bags directly from the makers. These eco-friendly, rustic souvenirs offer a meaningful way to support the local economy while taking a piece of Cao Bang's soul back home.

Located within a short drive from other traditional hubs like the Phuc Sen Blacksmith Village, Dia Tren is the perfect addition to a cultural exploration of the Northeast.
