Four Treasures of the Study, also called Four Jewels of the Study, refer to the brush, ink stick, paper and ink stone in Chinese. Each of them is an indispensable tool for Chinese calligraphy and Chinese painting.

In China, the history of brush can date back to 4000-5000 years ago; the ink was firstly used 3000 years ago; the ink stone was invented in the Spring and Autumn Period (770-476BC) and the paper was invented in the Eastern Han Dynasty (25 – 220 AD).

It is believed that the development of Chinese traditional culture and art are closely related to the development of the Four Treasures of the Study and to some extent, they were even an important part of the traditional Chinese culture.
