Luoyang

The name "Luoyang" originates from the city's location on the north or sunny ("yang") side of the Luo River. Since the river flows from west to east and the sun is to the south of the river, the sun always shines on the north side of the river. Luoyang has had several names over the centuries, including Luoyi (洛邑) and Luozhou (洛州), and Luoyang has been its primary name. It has also been called Dongdu (東都; 'eastern capital') during the Tang dynasty, Xijing (西京; 'western capital') during the Song dynasty, or Jingluo (Chinese: 京洛; lit. 'capital Luo'). During the rule of Wu Zetian, the only female emperor in Chinese history, the city was known as Shendu (神都; 'divine capital'). Luoyang was later renamed Henanfu (河南府) until regained its former name in 1912.

In 1036 BC a settlement named Chengzhou (成周) was constructed by the Duke of Zhou for the remnants of the captured Shang nobility. The Duke also moved the Nine Tripod Cauldrons to Chengzhou from the Zhou dynasty capital at Haojing. A second Western Zhou capital, Wangcheng (also: Luoyi) was built 15 km (9.3 mi) west of Chengzhou. Wangcheng became the capital of the Eastern Zhou dynasty in 771 BC. The Eastern Zhou dynasty capital was moved to Chengzhou in 510 BC. Later, the Eastern Han dynasty capital of Luoyang would be built over Chengzhou. Modern Luoyang is built over the ruins of Wangcheng, which are visible at Wangcheng Park. Qin Shi Huang's chief minister, Lu Buwei, was given Luoyang. Lu began programs to develop and beautify Luoyang. …
