Robin Hood is known for taking from the rich and giving to the poor—seizing the wealth of the rich to help the needy.
As for Hero Guo, his method was slightly different: he sold goods at exorbitant prices to wealthy people, usually targets dressed in luxury items, most of them young—this was the "taking from the rich" part. Then, he sold items at rock-bottom prices to people struggling to make ends meet—that was the "giving to the poor."
His specialty was scamming exclusively the rich.
