The car slowly navigated through the factory compound, Hu Weiwen proudly briefed them on the paper factory's situation: "Our factory produces five tons of copper plate paper every day!"
"Why do we need so much copper plate paper?" Tian Sisi didn't understand.
"Ah Nan, you're so naive. Of course, it's for printing the Red Treasure Books!" Tian Qinghua chuckled from the side.
"Oh!"
Tian Sisi didn't ask further. In this era, apart from the Red Treasure Book, there really weren't any other books to read. Almost everyone had a copy. With a population of seven or eight hundred million, just imagine, it's no wonder a small paper factory in Jining has to produce five tons of copper plate paper daily.
