Gan Luo 甘羅 was a grandson of Gan Mao 甘茂, counsellor in Qin 秦. When Lü Buwei 呂不韋, counsellor-in-chief of Qin 秦, planned to conquer more territory in the east, Gan Luo offered to go to Zhao 趙, the state whose territory should be attacked. Gan Luo convinced King Daoxiang of Zhao 趙悼襄王 (r. 244-236) to rather cede territory than to risk a war. He also pursued the king to unite with Qin to an alliance against Yan 燕, a state that had declined to wage war against Zhao.
