Xiao He
In 195 BC, Xiao He saw that Chang'an was becoming more congested and the imperial garden was full of uncultivated land, hence he suggested to Gaozu to carve out parts of the garden and grant them to peasants as farmland. Gaozu was unhappy and accused Xiao He of accepting bribes and dishonouring imperial authority. Xiao He was arrested and imprisoned, but was released later after Gaozu was convinced that Xiao He had the people's interests at heart. Gaozu summoned Xiao He to see him and he said with jest and embarrassment, "The chancellor was asking for the fields in the imperial garden out of interest for the people, but I did not approve. 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 imprisoned you to show the people that I'm a tyrant."
