Róng Design Library was founded by PINWU Design Studio in 2015. It is a non-profit organization and the first library in China focusing on traditional handcrafts and materials.
The core mission is to preserve the knowledge of Chinese traditional crafts and related materials. Furthermore, it offers a platform to deconstruct crafts, analyze materials and creating contemporary designs. Programs such as RONG Design Exhibition, Guest Designer Project and others were launched to share our vision to the public and among other creatives.
