How did the aunt of 72 tenants get rich?

Bagu shows shrewdness and philistinism in Seventy-two Tenants, and her main source of income comes from renting public houses and collecting rent.

First of all, stereotyped writing is a franchise company, which is her profession. At that time, many tenants had to pay rent to the charterer or lessee. As a lessee, Bagu will charge a certain rent to each tenant. These rents are my aunt's main source of income.

Secondly, stereotyped writing also obtains income from other channels. For example, she once sold some antiques, which further increased her wealth.

Generally speaking, Bagu's economic source mainly comes from her franchise and other investment channels.
