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.

The Territory of the Military Commander in Serbia (German: "Gebiet des Militärbefehlshabers in Serbien" ) was the area of the Kingdom of Yugoslavia that was placed under a military government of occupation by the Wehrmacht following the invasion, occupation and dismantling of Yugoslavia in April 1941.
 The territory included only central Serbia, with the addition of the northern part of Kosovo (around Kosovska Mitrovica), and the Banat.
 This territory was the only area of partitioned Yugoslavia in which the German occupants established a military government.
 This was due to the key rail and riverine transport routes that passed through it, and its valuable resources, particularly non-ferrous metals. On 22 April 1941, the territory was placed under the supreme authority of the German military commander in Serbia, with the day-to-day administration of the territory under the control of the chief of the military administration staff.
 The lines of command and control in the occupied territory were never unified, and were made more complex by the appointment of direct representatives of senior Nazi figures such as "Reichsführer-SS" Heinrich Himmler (for police and security matters), "Reichsmarschall" Hermann Göring (for the economy), and "Reichsminister" Joachim von Ribbentrop (for foreign affairs).
 The Germans used Bulgarian troops to assist in the occupation, but they were at all times under German control.
 Sources variously describe the territory as a puppet state, a protectorate, a "special administrative province", or describe it as having a puppet government.
 The military commander in Serbia had very limited German garrison troops and police detachments to maintain order, but could request assistance from a corps of three divisions of poorly-equipped occupation troops.
Liu Penzi (; born 10 AD) was a puppet emperor placed on the Han dynasty throne temporarily by the Red Eyebrows (Chimei) rebels after the collapse of the Xin dynasty, from 25 to 27 AD.
 Liu Penzi and his two brothers were forced into the Red Eyebrows as child soldiers.
 When the Red Eyebrows submitted to the new Emperor Gengshi of Han, his older brother Liu Gong fled to support the new emperor.
 Later, the Red Eyebrows rose again in rebellion and chose Liu Penzi as emperor.
 When they took Chang'an, Liu Penzi was officially Emperor of China, but he never had actual powers.
 When Liu Xiu definitively defeated the Red Eyebrows, he spared the 17 year old puppet emperor.
Mengjiang (Mengkiang; ; Hepburn: Mōkyō), also known in English as Mongol Border Land or the Mongol United Autonomous Government, was an autonomous area in Inner Mongolia, existing as a puppet state of the Empire of Japan under nominal Chinese sovereignty.
 Formed in 1939, it consisted of the then-Chinese provinces of Chahar and Suiyuan, corresponding to the central part of modern Inner Mongolia.
 It is occasionally called Mengguguo (or Mengkukuo; ) (in analogy to Manchukuo, another Japanese puppet state in Manchuria).
 The capital was Kalgan, and the ruler was Demchugdongrub.
The Museum of the Imperial Palace of the Manchu State () is a museum in the northeastern corner of Changchun, Jilin province, northeast China.

Emperor Shun of Liu Song ((劉)宋順帝) (467–479), personal name Liu Zhun (劉準), courtesy name Zhongmou (仲謀), nickname Zhiguan (智觀), was an emperor of the Chinese dynasty Liu Song.
 He became emperor in 477 after his violent older brother Emperor Houfei was assassinated by his attendant at the instigation of the general Xiao Daocheng, but in his brief reign was effectively Xiao's puppet.
 In 479, Xiao forced him to yield the throne to Xiao, ending Liu Song and starting Southern Qi.
 Later that year, the former Emperor Shun was killed by guards who were supposed to protect him, and the Liu clan was soon slaughtered as well.
Liu Menggeng () (1881–19??)
 was a politician and physician of the Republic of China and Manchukuo.
 He was born in Qinhuangdao, Hebei.
Manchukuo (: "Mǎnzhōuguó"literally: " State of Manchuria" ) was a puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy.
 The area, collectively known as Manchuria by westerners and Japanese, was designated by China's erstwhile Qing Dynasty as the "homeland" of the ruling family's ethnic group, the Manchus.
 In 1931, the region was seized by Japan following the Mukden Incident and a pro-Japanese government was installed one year later with Puyi, the last Qing emperor, as the nominal regent and emperor.
 Manchukuo's government was abolished in 1945 after the defeat of Imperial Japan at the end of World War II.
 The territories formally claimed by the puppet state were first seized in the Soviet invasion of Manchuria in August 1945, and then formally transferred to Chinese administration in the following year.
A puppet ruler is a person who has a title indicating possession of political power, but who, in reality, is controlled by outside individuals or forces.
 Such outside power can be exercised by a foreign government, in which case the puppet ruler's domain is called a puppet state.
 But the puppet ruler may also be controlled by internal forces, such as non-elected officials.

Question: In what year was the "puppet state" in which Liu Menggeng a politician/physician abolished?
