Yingqiu is a city located in the Shandong region of China. It serves as a geographical area within the province where historical sites related to the ancient Qi state are situated.
The region is notable for its proximity to the ruins of Linzi, which served as the capital of the Chinese Qi state. During the Spring and Autumn period, Linzi was recognized as one of the largest and wealthiest cities in China. The site gained further historical significance in 221 BC when King Ying Zheng of Qin occupied the city, completing his conquest of the rival states to declare himself the first emperor of China.
Archaeological excavations at the ancient ruins began in 1926 by Japanese archaeologists and were continued by Chinese archaeologists in 1964. These efforts have helped uncover the remains of the once-prominent urban center located in modern-day Shandong.
