What traditional Chinese culture is disappearing? Please give me some examples.

Qinqiang and Kunqu, the living fossils of Chinese opera, are rarely listened to nowadays! Who still imitates the excellent notes of the ancients in calligraphy and painting? Tea culture, originated in China, but famous in Japan, China is looking for coffee instead. Is it a decline? Some festivals, Dragon Boat Festival was copyrighted by South Korea, Tanabata Festival is not as hot as Valentine's Day, Chinese New Year is not as well-known as Christmas. This is not more representative of the decline? And porcelain culture - Sun Tzu Art of War - rituals and music ------
