The bamboo used for Liangping Bamboo Curtain Painting is the locally abundant Neosinocalamus affinis (commonly known as Ci bamboo) in Liangping, Chongqing.

The reason why Ci bamboo is chosen is mainly due to the following unique advantages:

• Excellent toughness for easy processing: Ci bamboo has long fibres and strong toughness. When making bamboo curtain paintings, the bamboo needs to be drawn into bamboo filaments as fine as hair. The toughness of Ci bamboo prevents it from breaking easily during splitting, meeting the requirements of such fine craftsmanship.

• Long bamboo nodes ensuring uniform filaments: Ci bamboo has slender nodes, with the longest reaching nearly one metre. Longer nodes mean a smoother bamboo surface, allowing longer and more uniform bamboo filaments to be drawn, which is crucial for weaving a flat, silk‑like bamboo curtain.

• Superior material for artistic quality: Ci bamboo has thin walls and a fine texture. The bamboo filaments produced are smooth, delicate, and have a soft, elegant colour. This provides a perfect "canvas" for painting, creating the unique aesthetic of Liangping Bamboo Curtain Painting — "thin as a cicada's wing, light as mist."

• Local availability ensuring fresh material: As a locally abundant bamboo species, sourcing it locally ensures freshness, allowing for "harvest and immediate use" to guarantee the best quality bamboo filaments.

In summary, the excellent characteristics of Ci bamboo make it an irreplaceable and ideal choice for producing the "finest bamboo curtain under heaven" — Liangping Bamboo Curtain Painting.
