Transmigrating to Ancient Times to Sell Tofu

There's a saying many people have joked about: "I wish I could smash my head against a block of tofu and die!" Dou Fu came from a tofu-making family with a legacy spanning more than a hundred years. And he really was killed by a block of tofu... When he opened his eyes again, Dou Fu, a man from the 21st century, had become Shen Fu, a sickly young farmer in a tiny mountain village. Shen Fu's family was truly miserable. There were barely a few grains of rice in the jar and not a drop of oil in the vegetables. The whole family was half-starved, scraping by on wild greens and millet. And the worst part? There were no soybeans or tofu here at all. How could he put up with that? Of course he couldn't. As the heir to a tofu-making family, the former Dou Fu, now Shen Fu, declared that even after transmigrating, he would still become the little prince of the tofu kingdom!
