Slowly become king, accumulate grain widely and build high walls. This is a famous saying of Zhu Yuanzhang, the founding emperor of the Ming Dynasty. It means: Don’t rush to become king and hegemony, accumulate grain extensively and build high walls. This sentence reflects Zhu Yuanzhang's wisdom and strategy, and is also one of the important reasons for his successful establishment of the Ming Dynasty.

1. First of all, "slowly becoming king" means not rushing to dominate the world. Zhu Yuanzhang was not very powerful at the beginning of the uprising, but he understood that becoming king too early would attract jealousy and attacks from other forces, and he would be embattled on all sides. Therefore, he chose to hide his ambitions temporarily, accumulate strength, and wait for the opportunity.

2. This strategy enabled Zhu Yuanzhang to develop stably in a turbulent era and eventually unify the country. Secondly, "accumulating grain extensively" means vigorously developing agriculture to ensure the country's food supply. Zhu Yuanzhang knew that the prosperity of a country was inseparable from the support of food, so he attached great importance to agricultural production.

3. Under his leadership, the Ming Dynasty implemented a series of policies conducive to agricultural development, such as reducing farmers' burdens, encouraging land reclamation, and building water conservancy projects. These measures greatly developed agricultural production in the Ming Dynasty and laid the foundation for the country's prosperity. Thirdly, "building the wall high" means strengthening national defense and safeguarding national security.
