Wang Chong (; 27 – c. 100 AD), courtesy name Zhongren (仲任), was a Chinese meteorologist, astronomer, and philosopher active during the Han Dynasty. He developed a rational, secular, naturalistic and mechanistic account of the world and of human beings and gave a materialistic explanation of the origin of the universe. His main work was the "Lunheng" (論衡, "Critical Essays"). This book contained many theories involving early sciences of astronomy and meteorology, and Wang Chong was even the first in Chinese history to mention the use of the square-pallet chain pump, which became common in irrigation and public works in China thereafter. Wang also accurately described the process of the water cycle.
As the center of the empire, early-Ming Nanjing had worldwide connections. It was home of the admiral Zheng He, who went to sail the Pacific and Indian Oceans, and it was visited by foreign dignitaries, such as a king from Borneo (Boni 渤泥), who died during his visit to China in 1408. The Tomb of the King of Boni, with a spirit way and a tortoise stele, was discovered in Yuhuatai District (south of the walled city) in 1958, and has been restored.
Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds.

Question: What visiting king died in 1408 in the country where the person who could describe the process of evaporation was from?
Answer: (Boni 渤泥)
Although, in a general way, the formative ideas behind the imperial exams can be traced back at least to Zhou dynasty times (or, more mythologically, Yao), such as imperial promotion for displaying skill in archery contests, the imperial examination system in its classical manifestation is historically attested to have been established in 605, during the Sui dynasty; which in the quickly succeeding Tang dynasty was used only on a relatively small scale, especially in its early phase. However, the structure of the examination system was extensively expanded during the reign of Wu Zetian: the impact of Wu's use of the testing system is still a matter for scholarly debate. During the Song dynasty the emperors expanded both examinations and the government school system, in part to counter the influence of military aristocrats, increasing the number of those who passed the exams to more than four to five times that of the Tang. Thus the system played a key role in the selection of the scholar - officials, who formed the elite members of society. During the Ming and Qing dynasties, the system contributed to the narrowness of intellectual life and the autocratic power of the emperor. The system continued with some modifications until its 1905 abolition under the Qing dynasty. Other brief interruptions to the system occurred, such as at the beginning of the Yuan dynasty in the 13th century. The modern examination system for selecting civil servants also indirectly evolved from the imperial one.

As of April 30, 2018, debt held by the public was $15.3 trillion and intragovernmental holdings were $5.7 trillion, for a total or ``National Debt ''of $21 trillion. Debt held by the public was approximately 77% of GDP in 2017, ranked 43rd highest out of 207 countries.

As of December 2017, $6.3 trillion or approximately 45% of the debt held by the public was owned by foreign investors, the largest being China (about $1.18 trillion) then Japan (about $1.06 trillion).

Book censorship in the People's Republic of China (PRC) is implemented or mandated by the PRC's ruling party, the Communist Party of China. Book censorship is widespread in China. Enforcement is strict and sometimes inconsistent. Punishment for violations can result in prison. The Chinese government is extremely sensitive to any opinions on the politics and history of China and its leaders that differ from currently sanctioned opinions, or that discuss topics which are officially taboo. What is officially taboo can change over time.

After conquering "China proper", the Manchus identified their state as "China" (中國, Zhōngguó; "Middle Kingdom"), and referred to it as Dulimbai Gurun in Manchu (Dulimbai means "central" or "middle," gurun means "nation" or "state"). The emperors equated the lands of the Qing state (including present day Northeast China, Xinjiang, Mongolia, Tibet and other areas) as "China" in both the Chinese and Manchu languages, defining China as a multi-ethnic state, and rejecting the idea that "China" only meant Han areas. The Qing emperors proclaimed that both Han and non-Han peoples were part of "China." They used both "China" and "Qing" to refer to their state in official documents, international treaties (as the Qing was known internationally as "China" or the "Chinese Empire") and foreign affairs, and "Chinese language" (Dulimbai gurun i bithe) included Chinese, Manchu, and Mongol languages, and "Chinese people" (中國之人 Zhōngguó zhī rén; Manchu: Dulimbai gurun i niyalma) referred to all subjects of the empire. In the Chinese-language versions of its treaties and its maps of the world, the Qing government used "Qing" and "China" interchangeably.

The Song dynasty is divided into two distinct periods, Northern and Southern. During the Northern Song (Chinese: 北宋; 960 -- 1127), the Song capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now Eastern China. The Southern Song (Chinese: 南宋; 1127 -- 1279) refers to the period after the Song lost control of its northern half to the Jurchen Jin dynasty in the Jin -- Song Wars. During this time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional ``birthplace of Chinese civilization ''along the Yellow River, the Song economy was still strong, as the Southern Song Empire contained a large population and productive agricultural land. The Southern Song dynasty considerably bolstered its naval strength to defend its waters and land borders and to conduct maritime missions abroad. To repel the Jin, and later the Mongols, the Song developed revolutionary new military technology augmented by the use of gunpowder. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the city of Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan, though his claim was only partially recognized by the Mongols in the west. In 1271, Kublai Khan was proclaimed the Emperor of China. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279. The Mongol invasion led to a reunification under the Yuan dynasty (1271 -- 1368).
According to "The Secret History of the Mongols", Chabi was the favorite wife of Kublai and a valued unofficial adviser throughout his reign.
