Gaozu also granted Xiao He a rare special privilege: Xiao was allowed to enter the imperial court carrying a sword and with his shoes on, and not required to walk in briskly while others had to. In service during the Western Han dynasty In 201 BC, Emperor Gaozu wanted to build his capital in Luoyang but Zhang Liang suggested Xianyang instead, because it was surrounded by natural defences such as mountain passes, and had fertile land for agriculture.

This showed that I'm only like Jie and Zhou (Emperors of the Xia and Shang dynasties), and that you're the most understanding chancellor. Therefore, I intentionally
