Taizi River

The Taizi River (Chinese: 太子河) is a major river in the Liaoning province of Northeastern China. The river was historically also known as Yan River (衍水) or Liang River (梁水). It was originally the third-largest tributary of the Liao River, southern Northeast's principal river, draining with the neighboring Hun River into a confluence known as "Trident River" near Haicheng, until a river engineering project in 1958 cut off the eastern distributary of the river delta from the Liao River's main course, making the Hun River and Taizi Rivers a separate system that drains into the Bohai Bay independently from the Liao River. However, both sister rivers are still usually considered a part of the Liao River system because they are both within the historical Liao River drainage basin.
