Where is the monarch who rules the most?

Yongcheng was the capital of Qin State in China during the Eastern Zhou Dynasty (now Fengxiang District, Baoji City, Shaanxi Province). From the first year of Qin Degong (677 BC) to the second year of Qin Xiangong (383 BC), it was established in 294, and 19 Qin Guo Jun was in power here, which was the longest time for Qin to establish its capital.

Yongcheng is a "city cut by the river" with the river as its city and a "Qin Dou on the water". After 200 years of defending the enemy with water, Qin first built the city wall. Qin Yongcheng site is one of the top ten archaeological discoveries in China. In the fourth year of Qin Wengong (762 BC), Qin won the "Thousand Wei Hui" (now south of the intersection of chencang district and He Qian in Baoji City, Shaanxi Province) and settled in Guanzhong, the hometown of Zhou people. After Qin occupied the "Thousand Wei Hui", it built a city here.
