Liu Ba (Three Kingdoms): Liu Ba (died 222), courtesy name Zichu, was an official in the state of Shu Han during the Three Kingdoms period of China.  He originally served under the warlord Liu Zhang before becoming a subordinate of Liu Bei (the founding emperor of Shu) after Liu Zhang's surrender to Liu Bei in 214.  Liu Ba was instrumental in helping Liu Bei reward his subordinates from the treasury without impoverishing the common people after their conquest of Yi Province.  Liu Ba also helped write the "Shu Ke" (蜀科), the legal code of Shu, along with Zhuge Liang, Li Yan, Mi Zhu, Dong He and others.  Liu Ba succeeded Fa Zheng as the Prefect of the Masters of Writing in 220 and held office until his death in 222.

Mi Zhu: Mi Zhu ( 165-221), courtesy name Zizhong, was an official and adviser who served under the warlord Liu Bei in the late Eastern Han dynasty, during the Three Kingdoms period, after Liu Bei founded the state of Shu Han.  He was also Liu Bei's brother-in-law, as his sister, Lady Mi, married Liu Bei.  Mi Zhu was essential to Liu Bei during the defeats of the latter, financing Liu Bei's army in critical times where there was no tax base.  Mi Zhu was extremely well educated and helped Liu Bei develop relationships with wealthy rivals like Yuan Shao, Yuan Shu and Liu Biao.  He was also the elder brother of Mi Fang, who served Liu Bei as well until his defection to Liu Bei's ally-turned-rival Sun Quan in 220.  Mi Zhu served Liu Bei loyally for more than 25 years, as a high civil official of Liu during all the later's tenures as governor of Xu, Jing, and Yi provinces,the former's ideas were regularly and widely circulated to the common people which greatly helped Liu Bei's political movement as Han loyalist and Confucian but, historians would argue it mere rhetoric as Liu ruled more in the tradition of legalism.  Nonetheless, Mi along with Jian Yong, Sun Qian, and later Yi Ji, greatly contributed to the Liu's populist movement to restore the Han dynasty through literature and essays.  Mi Zhu was thought to be Liu's best friend and most favored subject, he died of illness a little over a year after Liu Bei declared himself emperor.

Pearl River (China): The Pearl River, also known by its Chinese name Zhujiang and formerly often known as the Canton River , is an extensive river system in southern China.  The name "Pearl River" is also often used as a catch-all for the watersheds of the Xi ("West"), Bei ("North"), and Dong ("East") rivers of Guangdong.  These rivers are all considered tributaries of the Pearl River because they share a common delta, the Pearl River Delta.  Measured from the farthest reaches of the Xi River, the Pearl River system is China's third-longest river, 2400 km , after the Yangtze River and the Yellow River, and second largest by volume, after the Yangtze.  The 409480 km2 Pearl River Basin (珠江流域 ) drains the majority of Liangguang (Guangdong and Guangxi provinces), as well as parts of Yunnan, Guizhou, Hunan and Jiangxi in China; it also drains northern parts of Vietnam's Northeast Cao Bằng and Lạng Sơn provinces.
