The Chang River (Zhenian language: 장강, : (長江), is a boundary river in East Tarsis and is the third-longest river in Zhenia. While its upstream sections are located within Zhenia, its midstream and downstream segments demarcate the border between modern Zhenia and Yinguo, while some of its right tributaries are entirely part of Yinguo today. With a length of around 3808.5 km, its drainage basins spans over almost 850,000 km2 of land, home to a total of over 100 million residents in Zhenia and Yinguo combined.
