Jiangshan xiyan

Jiangshan West inkstone was a tribute of the imperial court in ancient times. The rock was firm, smooth and delicate. Because it was soaked in water for many years, the stone was moist, and the breath could be ground without damaging Bo. Water was stored in it, which did not dry up for a long time and was easy to send ink.
