Ancient Linzi
Zibo, China
Linzi (pinyin: Línzī) was the capital city of the Chinese Qi state. The ruins of the city lie in modern-day Linzi District, Shandong, China. The city was one of the largest and richest in China during the Spring and Autumn period. Upon occupying Linzi in 221 BC, King Ying Zheng of Qin completed his conquest of the Chinese rival states and declared himself the first emperor of China shortly afterwards. The ruins of the ancient city were excavated in 1926 by Japanese archaeologists and in 1964 by Chinese archaeologists.
