A short soft brush connected to a long hard handle, both vigorous and gentle — a simple Chinese writing brush can describe the most sophisticated idea. Achieving both technical excellence and spiritual freedom in writing, a good brush allows for unrestrained creativity and endless variation.

A brush can reveal a dot, a line, the sun, the moon, mountains, rivers, wind and everything people can sense in the world, slender or thick, big or small, concrete or abstract.

Perhaps it is one of the few tools invented by humans that is so practical yet so rich in symbolic meanings over millennia. It not only conveyed common people's care and emotions, but also recorded history, narrated thoughts, and created the most refined art and literature of this culture, thus greatly influencing the development path of Chinese civilization.
