Torii Ryuzo saw cou woman making pottery in tapangx tribe in 1898 and took a picture of it, noting:’’cou woman have a high degree of pottery, but now there are only 2 women left to make pottery. I think after the pass away of these two remaining women, cou’s ancient pottery skills will be lost’’Regrettably, as Torii Ryuzo predicted it, the cou gradually forgot about traditional pottery and even called it ’kavo’oe’, which is derived from Hen/Hokkien language. Cou people has long forgotten its ancestral pottery culture, mainly because substitutes are easily available, durable, large in production, fast in production and low in price. This trend is related to the reclamation of Han Chinese in modern times, the leasing of land and the opening of the Alishan Forest Railway. The original pottery of the cou people has disappeared from life and is only found in museums. However, after 1990, the indigenous people tried to revive the culture and language, and in addition, cou people with the introduction of exotic crops such as tea and coffee trees, it gradually became an important industry of the cou people, indirectly causing the reproduction of pottery. Through documentation, fieldwork, and visits to museum collections, this article confirms the original clay collection, pottery tradition of the cou people, hopes to know the origin of cou pottery techniques, and clarify that the name of cou pottery has changed from kuyayanx to kavo’oe, and now gradually becomes the possibility of soethui(drinking cup), hoping that it will accompany the emerging industry of the cou people.
