Jialiang () is an ancient Chinese measuring device for several volume standards. The term jialiang is mentioned in the ''Rites of Zhou''. The passage describes the construction of one that includes three measures, ''fu'' (釜), ''dou'' (豆), and ''sheng'' (升); furthermore, the instrument weighs one ''jun'' (鈞) and its sound is the ''gong'' of ''huangzhong'' (黃鐘之宮).〔''Kaogongji'' 考工記 45-47. (Chapter at Chinese Text Project )〕 Known jialiang give standards for the five measures yue (龠), ge (合, equal to two yue), sheng (升, equal to ten he), dou (斗, equal to ten sheng), and hu (斛, equal to ten dou). The earliest known jialiang was made in the first year of Wang Mang's short-lived Xin Dynasty (9-23 CE), in order to standardize the measurements across the empire. Wang chose bronze to emphasize that it would last and remain as a reference. A 216-character inscription records the process of the casting and shows where each of the five measurements can be found. Wang Mang's jialiang is now in the National Palace Museum, Taipei.〔(Bronze Jia Liang ) at the Carnegie Mellon University Libraries LUNA commons collection〕 In Beijing's Forbidden City, before the Hall of Supreme Harmony and the Palace of Heavenly Purity, there are two jialiangs cast during the reign of the Qianlong Emperor, a square one in front of the Hall of Supreme Harmony and a round one in front of the Palace of Heavenly Purity. These were cast in 1745 based on an examination of the Wang Mang's round jialiang and the square jialiang made during in the time of Emperor Taizong of Tang.〔(嘉量 ) at the Palace Museum website.〕 The jialiang and the adjacent sundial (''rigui'' 日晷) have been described as symbolizing the sovereignty and unity of the imperial reign〔(Jialiang ) at tripchinaguide.com〕 or emphasizing that the emperor is just and fair.〔(Hall of Supreme Harmony ) at TravelChinaGuide〕 ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jialiang」の詳細全文を読む スポンサード リンク
