her womb. Emperor Jing was ecstatic over the divine implication, and made Liu Che (his 10th son) the Prince of Jiaodong (膠東王) in May 153 BC. Wang Zhi was also promoted to a consort for giving birth to a royal prince. Emperor Jing's formal wife, Empress Bo, was childless. As a result, Emperor Jing's oldest son Liu Rong (劉榮), born of the Emperor's other favourite concubine, Lady Li (栗姬), was created crown prince in May 153 BC. Lady Li, feeling certain that her son would become the emperor, grew arrogant and intolerant, and frequently threw tantrums at Emperor Jing out of jealousy over his favouring of other concubines. Her lack of tact would prove to be Consort Wang's chance. When Emperor Jing's older sister, Elder Princess Guantao (館陶長公主) Liu Piao (劉嫖), offered to marry her daughter Chen Jiao (陳嬌) to Liu Rong, Lady Li rudely rejected the proposal, complaining that Princess Guantao often offered new concubines as prostitutes to Emperor Jing. Angered by this snub, Elder Princess Guantao encouraged Emperor Jing not to favour Lady Li. Consort Wang, who had been observing quietly and waiting for her chance, took the opportunity and secured a marriage alliance by offering to marry her 5-year-old son Liu Che with Chen Jiao. Now siding with Consort Wang, Princess Guantao constantly criticised Lady Li in front of Emperor Jing. Gradually accepting his sister's concerns, Emperor Jing decided to test out Lady Li. One day he asked Lady Li that whether she would happily look after and properly raise the rest of his children if he was to pass away, only to have Lady Li rudely (and foolishly) refuse to comply. This made Emperor Jing angry and he became worried that if Liu Rong was to inherit the throne and Lady Li became Empress Dowager, many of his concubines might suffer the fate of Consort Qi. Seizing the opportunity, Consort Wang put in place the final straw against Lady Li. She persuaded a minister to advise Emperor Jing to make Lady Li empress as Liu Rong was already the crown prince. Emperor Jing, already of the view that Lady Li must not be made empress, was enraged and believed that Lady Li had conspired with government officials. He executed that minister who put forward that proposal, and demoted Liu Rong to the Prince of Linjiang (臨江王) in 150 BC and exiled him out of the capital
