Shi Huang was born in Handan, the child of a statesman from the state of Qin and after successfully conquering Zhao he ordered all enemies of his mother to be buried alive. The conquest of Zhao, particularly the Qin siege of Handan, is featured extensively in Chen Kaige's classic film, The Emperor and the Assassin. At the beginning of the Han dynasty, Handan was Liu Bang's base for suppressing Chen Xi's rebellion in 197 and 196 BCE; it was still regarded as a regional center of culture and commerce at the end of the dynasty in the early 3rd century CE. It slowly declined, perhaps because of the numerous battles that ravaged northern China following the Han Dynasty, but maintained a reputation for its fine Cizhou ware well into the Qing dynasty (1644–1911). It was also the birthplace in the 19th century of Yang-style tai chi, one of Tai Chi's five major schools. Though much of Handan's ancient history is no longer visible, it still has some attractions, deriving from the many Chinese idioms that the city inspired, such as the road into which Lin Xiangru, courier of the precious Heshibi, backed in order to let his nemesis Lian Po pass first, as well as the location in which Lian Po begged for Lin Xiangru's forgiveness. Modern-day Congtai Park is located on the site of the historical Zhao court. Next to Congtai Park is the legendary "Xuebu Bridge" (), or "Learning to Walk Bridge". Legend has it that a noble from the state of Yan heard of a particularly elegant manner of walking unique to Handan. Arriving in Handan, he spent weeks trying to master the Handan style of walking on a bridge, only to fail. In the process, however, he had forgotten how to walk normally and had to crawl back to Yan. This story inspired the Chinese expression, "to learn the walk of Handan" (, Hándān xué bù), which means learning something difficult too intensely, thereby forgetting the basics in the process. The nearby Xiangtangshan Caves contain massive Buddha statues carved into the mountainside, some dating to the 6th century, many of which were severely damaged by invading Japanese forces during World War II. At that time, Handan was prized by the Japanese invaders for its coal reserves. In 2007, Handan was the location of China's largest-ever bank robbery.
