You should know that this jade mine has been excavated for almost over fifty years now.
The Gu Family's jade mining is of a nature where they nurture while extracting.
Miners only need to work for a few months each year, and during the rest of the time, the Gu Family's jade mine would be in a state of recuperation and regeneration.
During this period, the miners' wages would still be paid as usual.
That is to say, the Old Patriarch was nurturing both the jade mine and the workers.
This is also part of why Yubao Square became the leader in the industry.
Even if it had changed hands in the past, eventually, it returned to the control of Gu Qingfeng.
Although the jade mine paid hefty taxes every year, after all, that was a minor concern.
It could be said that the jade mine is a pillar supporting both the Jade Carving Workshop and Yubao Square.
If this pillar were to collapse, then Yubao Square would truly become an ordinary antique shop.
