Marquis of Bailu counted as one of the top aristocratic families in the Tang Empire. If wealth alone were to be considered, they might rank even higher.
After all, the Tang Empire had only been established for just over a decade and hadn't had the time to solidify a real aristocracy, so most of the so-called noble families were outsiders.
There was no need to mention the Royal Family. Although they were incomparably noble, there were no more than six people who could truly be called royals – nowhere near the scale of other empires, with their hundreds or thousands of extended royal relatives dragging along.
The remaining Ministers were "lone wolves," still too early in their careers to develop family enterprises: some military officers had only recently established households, their children still ruling the roost in elementary school.
