#Didyouknow: To make the calligraphy pen, the bamboo is cut at a thirty-degree angle and split in half from top to bottom. Even with the technology present today, it is not possible to write better or more beautifully using anything other than bamboo. The squeaking sound you hear when using the bamboo pen is said to be the weeping of the pen. It is said that the pen weeps so as to not fall into the hands of the ignorant.
