Is Silk Porcelain Tea the quintessence of China?

National quintessence refers to the essence of a country's inherent culture. In China, national quintessence refers to the most representative and unique cultural heritage of the Chinese nation, which is often welcomed by people. China Wushu, Chinese Peking Opera, China Painting and China Medicine, which are well-known at home and abroad, are called "the four quintessences of China" by the world. This shows that silk, porcelain and tea are not the quintessence of China at present, because foreign countries also have non-inherent cultures. thank you
