Chu Zhuo 觸讋 or Chu Long 觸龍 was a minister of Zhao 趙. Just after the accession of King Xiaocheng 趙孝成王 (r. 265-245) to the throne, when Queen Dowager Wei 趙威后 still reigned for him, Qin 秦 wanted to attack Zhao. Zhao called for help with Qi 齊, but the king of Qi asked to hand over Prince Chang'an 長安君 as a hostage. The Queen dowager wanted to decline, but Chu Long persuaded her to do so for the sake of the country.
