Hangu Pass
In 301 BC, Qin again attacked Han, led by King Zhaoxiang's uncle, Wei Ran, and occupied the city of Rang (穰城). The city was later given to Wei Ran, who was made chancellor six years later, as his fief. However, in 298 BC, Qin suffered a setback at Hangu Pass under the combined attack from a three-state alliance of Qi, Han and Wei, and was forced to concede the recently occupied Fengling and Wusui back to Wei and Han.
