During the Revolution of 1911, the protagonist Shengde, a farmer, happened to save Huang Xing, a follower of Sun Yat-sen. The two had a heart-to-heart talk. Inspired by the theory of saving the country through industry, in order to pursue the dream of making a fortune through industry, they invited all their neighbors to jointly purchase the old equipment from the oil mill in the neighboring village that had suffered a fire. They worked together to build the oil mill. According to rural customs, on the day when the beam was laid, a beam sacrificial ceremony was held, which was a lively and festive event.
