"The Yangyang Yue Kingdom is in ancient Mingzhou, and its door faces the great river." It's the Yao River. Ningbo was born and prospered because of rivers. Fenghuajiang, Yaojiang and Yongjiang rivers flow through the city. The large river flowing across the door refers to the elegant and quiet Yaojiang River along the river bank. It is the Yaojiang River, the longest and clearest water in Ningbo, that fits Ningbo's city-building concept of "facing the great river flow" since ancient times.
