Previously, when the Wanfeng Grain Store sold oil, customers had to bring their own containers.
Now, the Wanfeng Grain Store provided standardized porcelain jars for the peanut oil, each designed to hold exactly two catties.
At first, Steward Jia didn't quite understand.
Custom-ordering the jars increased their costs, yet the price of the peanut oil sold by the Wanfeng Grain Store remained unchanged.
The result was a decrease in profits.
He felt the Princess Consort's move was completely unnecessary.
However, the introduction of the porcelain jars strengthened the public's recognition of the Wanfeng Grain Store brand. Eventually, whenever people thought of buying peanut oil, the first name that came to mind was always Wanfeng.
Even when several other grain stores later began selling peanut oil, many people still considered only Wanfeng's to be the most authentic.
