In 10 century BC, Zhou Muwang acceded to the throne. Zhou Muwang is a person who likes to travel and explore. He is determined to travel around the world so that he can be found everywhere. During the Warring States Period, there was a book called Biography of Mu, which told the story of his traveling around the world. It is said that on one occasion, Zhou Muwang took a car pulled by eight fine horses and was driven by Zhao Fu, the most famous driver in the history of China. After passing through Zhanghe and Zhang Lun, he left Yanmenguan and went west. They walked thousands of miles and arrived at a place where a tribe called Juthough lived, and were treated with the highest courtesy by the local people. People in this tribe invited Zhou Muwang to drink the blood of pigeons and wash his feet with milk from cows and horses.
Scholars who study the history of the Zhou Dynasty believe that the route of Zhou Muwang's Western Expedition started from Luoyang, went north through Zhanghe and Zhang Tuo, went out of Yanmenguan, and then turned west to southwest, reaching today's Jishi Mountain in Qinghai. Then, they went west, along the northern foot of Kunlun Mountain, crossed the Pamirs, arrived at Chiwu in the west of Hindu Kush Mountain today, and arrived at the city-state of the Queen Mother of the West, which is now Tehran, Iran. Then, Zhou Muwang went north, crossed the Caucasus, entered the Great Plains of Eastern Europe, and arrived in Warsaw. Finally, they passed Lake Ladoga, Volga River, Weihai, Lake Issyk Kul, Mongolian Desert and Taihang Mountain near Finland today and turned around and returned to Luoyang.
It seems that Zhou Muwang should be the first person to explore the west in the history of China, and also the farthest person.
