Mrs. Zhang had followed Gu Baofu for so many years, but she'd never seen him bring back much silver. On the contrary, his younger brother Gu Ya was much better at making money.
In the past, despite Gu Ya being bedridden with his legs disabled, people would still bring money to him to earn, and even Fuman Building, that large restaurant, would send their ledger to him.
Mrs. Zhang had inquired elsewhere and found out that Fuman Building paid Gu Ya well for keeping their books. No wonder that couple now had the silver to repair their house.
If Gu Ya could make money with his legs disabled, now that his legs were fine, wouldn't he be even more formidable at earning? She guessed that he must be watching gleaming silver coins pouring into his purse all day long.
The more Mrs. Zhang thought about it, the more useless she found her own husband.
