King Wen took eight hundred steps with a rickshaw. Is it true in the 800-year history of the Zhou Dynasty?

"King Wen pulled a rickshaw for 800 steps, and the Zhou Dynasty lasted for 800 years" means that Xibo Hou Jichang was eager to visit Xian after being imprisoned in Yin for three years. I heard that Jiang Shang lived in seclusion by the Weihe River, so he drove to visit. In their conversation, Ji Chang saw that Jiang really knew how to hide his strength and bide his time, so he invited him to assist Zhou Bang. In order to test his sincerity in seeking talents, Jiang Shang asked him to pull a rickshaw for him before allowing him to go on the road. Ji Chang was eager to seek the virtuous, so he pulled a rickshaw for Jiang Shang, so the monarch and his subjects left Weishui together.
