From Zhu Yuanzhang's advice to Zhu Sheng, a bachelor, on his strategic policy of pacifying the world, Zhu Sheng said: "Build a high wall, accumulate grain widely, and slow down to be king."

Extended data:

In A.D. 1356, the water army of the Yuan Army was annihilated by Zhu Yuanzhang in Quarry Collection, and the Yuan Army surrendered in Qing Ji City, and Zhu Yuanzhang successfully entered Qing Ji. He changed his name to Yingtianfu, Qing Ji, and has a relatively stable and promising base since then.

Zhu Yuanzhang felt that his strength was not strong enough, so although Zhang Shicheng, Chen Youliang and Fang Guozhen, which occupied Zhejiang, Sichuan and Huguang at this time, were already kings, Zhu Yuanzhang only silently strengthened his strength. In Taiping, he only set up the Marshal's Office of Taiping Xingguo Wing, and in Jinling, he was just called Wu Guogong.

He is also very aware of the importance of food and other materials to support his regime and military activities. Despite his busy military affairs, he always cares about local agricultural production and encourages farming and sericulture wherever he goes. He arranged for the army to cultivate grain, which was called wasteland reclamation. Appoint officials to be responsible for building dams, building water conservancy projects and ensuring the supply of rations.

In Huizhou, Zhu Yuanzhang asked Zhu Sheng, a bachelor, for his future strategic policy. Zhu Sheng said: "Building a wall is high, accumulating grain is wide, and it is slow to be king." This actually summed up Zhu Yuanzhang's consistent policy, and he was very happy. It was under this policy that Zhu Yuanzhang completed the unification of China imperial industry step by step.
