Nirvana in Fire Episode 9

After Mei Changsu moves into his new house, Prince Yu visits and asks him to help him save Duke Qing. However, Mei advises him to drop the Duke, and instead support Prince Jing. After much persuasion, Prince Yu agrees. The next day, Mei goes to see Prince Jing to help him prepare for the case as well as the future, such as keeping capable and neutral officials as acquaintances. Prince Yu and Prince Xian argue against each other about who would replace Lou Zhijing as Minister of Revenue. After they were dismissed, the Emperor hears about Shen Zhui, a third-rank official who is currently running the department in Lou's absence. (Source: Wikipedia)
