Lu Zheng took a turn at the Sweet Shop.
At this time, the Sweet Shop wasn't as lively as it was on its opening day, but because it only sold high-end rock sugar, as long as a transaction was made, the income was considerable.
Plus, the quality of their rock sugar was absolutely top-notch, so many wealthy families specifically bought rock sugar from the Sweet Shop, making it a long-term business.
Nowadays, after deducting rent and labor, the Sweet Shop could provide Lu Zheng with an income of one thousand coins almost every day, which translates to a purchasing power equivalent to a thousand dollars in modern terms.
Don't underestimate this one thousand coins; one per day amounts to the price of Lu Zheng's three-entry courtyard in a year, something many commoners could never afford in a lifetime.
