 Han Xin is best remembered as a brilliant military leader for the strategies and tactics he employed in warfare, some of which became the origins of certain Chinese idioms.In recognition of Han Xin's contributions, Liu Bang conferred the titles of "King of Qi" on him in 203 BC and "King of Chu" in the following year.However, Liu Bang feared Han Xin's growing influence and gradually reduced his authority, demoting him to "Marquis of Huaiyin" in late 202 BC.
