Which can better represent the artistic and cultural color of China, guzheng or pipa?

The history of the two guzheng historical studies is longer than that of pipa, but the influence of pipa on Asia is far greater than that of guzheng! However, the influence of guzheng in China is greater than that of pipa, so it can better represent the artistic and cultural color of China. However, I think the individual who truly represents China culture thinks it is Guqin, representing China's ancient thoughts! The thought of peace, tranquility and freedom of Chinese descendants is contained in it.
