Traditional Asian painting on non-absorbent Chinese paper with mica flakes. The work is mounted on "Moon Palace" paper. Bamboo is in monochrome, not black as is common in museums, but with a bronze green gradient. Pigments are minerals diluted in water and a small bowl of Chinese porcelain: all tones are collected, from the lightest to the darkest: it is the academic technique with twelve passages of colour to obtain the fibres of this bamboo cane and these leaves that seem to move before our eyes! The knots are drawn with Chinese ink stick crushed in a DUAN ink stone (Guangdong - southern China) and diluted in water. The "IQ" vital energy of the work is represented by the blue dragonfly. Blue is that of a mineral pigment from Taiwan (also diluted in water). Bamboo symbolizes robustness and flexibility, as well as righteousness "to be right in words and deeds". The seal of the signature in cinnabar red is at the bottom right.
