Ru ware celadon possesses a unique glaze color, subtly blending green into its blue-green hue. Its texture is as smooth as silk, light yet understated. Distinct from other celadon, its glaze is as warm and gentle as jade, yet transcends the beauty of jade. The celadon glaze is extremely precious, and its feel is also like that of jade. Ru ware pieces are regarded as treasures in the history of Chinese ceramics, possessing exceptionally high artistic, historical, and cultural value.

The renowned Japanese writer Yasunari Kawabata once collected Ru ware celadon, pieces which are now preserved in the Tokyo National Museum. He held Ru ware in high esteem, deeply moved by its aesthetic value, a sentiment he expressed in his literary works. Kawabata referred to Ru ware as the "king of celadon," believing that its glaze embodied a profound artistic conception that resonated with the human soul. He also noted that its exquisite color and luster conveyed the very essence of natural beauty.

Legend has it that one day, Emperor Huizong of the Song Dynasty in China had a dream. In the dream, after a heavy rain, the sky cleared, revealing a dazzling celadon blue.
