Anyone is fine, but calligraphy cannot be passed as an art test, so I’ll stick with guzheng.

Guzheng, a plucked string instrument, also known as Han Zheng and Qin Zheng, is an ancient national musical instrument of the Han nationality and is popular throughout China. It is often used as accompaniment for solos, ensembles, instrumental ensembles, singing and dancing, opera, and folk arts. Because of its wide range, beautiful timbre, rich playing skills and strong expressiveness, it is called the "King of Music" and also known as the "Oriental Piano". It is one of China's unique and important national musical instruments.
