Four hundred years before modern interactive design became a trend, a remarkable ceramic crab was already captivating audiences in ancient China. Between 2018 and 2022, archaeologists unearthed the cup in the ruins of Zhouqiao Bridge along the Bianhe River in Kaifeng city, located in today’s central Chinese Henan province. Kaifeng was the capital of eight dynasties in Chinese history and served as a secondary capital during the early Ming dynasty (1368–1644). Discovered between 2018 and 2022 in the ruins of Zhouqiao Bridge by the Bianhe River in Kaifeng, Henan province, this charming Ming dynasty interactive ceramic wine cup dates back hundreds of years.
