Because of fairness, mountain cells jump with joy. Yu Yonghe recorded the method and process of sulfur smelting in detail, as well as the details of pit exploration. The language he recorded is very vivid, lively and true, and it is a wonderful essay. Here's an example: "Grass grows a path only for snakes, and Gu Jun wins with tools. He is a guide and he is a follower. Within five steps, he didn't see each other, worried or lost, and each listened to the echo. About two or three miles across two streams, all involved. Re-entering the forest, dense trees, indistinguishable size ... re-entering the steep Sakamoto, worth five or six streams. The stream is four or five feet wide, and water gurgles among the stones. It's all indigo with stones. It is said that this water source is a boiling spring under the sulfur cave. I tried it with my fingers, too, and it was still very hot.

Once, he was awakened after sleeping late into the night and found that 18 arrows had shot into the pillow. He was intact in the rain of arrows. They were in the land of plague, and all the people he took were sick and died. Sometimes when there is a strong wind, the house collapses and the household appliances are destroyed, so we have to start a new stove. This is a fearless and brave action. Yu Yongwen finally made 500,000 Jin of sulfur and shipped it back to his job, and created A Journey to the Sea (also known as Diary of Picking Sulfur), a brilliant prose work in the literary history of Taiwan Province Province.
