三倍倍投利润表

简介：The Zhenlu Factory was originally designed to work in two shifts and operate around the clock. This was indeed the case for the first two years of production. However, in recent years, the imperial court had financial difficulties and the amount of money allocated was getting less and less year by year. Coal was not in supply, so Zhenlu Factory only fired during the day, and at night there was no one in the entire factory area.
