During the Battle of Changping, he became the commander of Zhao. Deciding not to risk his forces by engaging in open battle with the Qin, under their brilliant general Bai Qi, Lian Po instead built a series of forts along the Changping area, successfully stopping the invasion of Qin. However, King Xiaocheng of Zhao (趙孝成王), under the persuasion of many courtiers (most of whom were bribed heavily by Qin spies) became dissatisfied with Lian Po's strategy, and decided to replace him with Zhao Kuo (趙括). Being the son of another famous Zhao general, Zhao She, Zhao Kuo discarded Lian Po's cautious, defensive strategy and attacked with full strength. As a consequence, he was defeated, and Zhao never returned to prominence.
