Judy, the founder of the Ming Dynasty, was the third emperor of the Ming Dynasty. During his administration, he made many contributions to the development of China's history. He effectively governed the frontier and promoted the unity and development of China's multi-ethnic countries. He actively developed and operated the northeast region, established a famous slave capital department in history, and formally incorporated a large territory in the middle and lower reaches of Heilongjiang into Chinese territory. At that time, four passages were built on the circular road of Nuer Tuotu, and there were post stations for business travelers along the way. These four passages connect Liaodong and Beijing in the south. The means of production and living in the mainland are continuously transported to the local ethnic minorities in Northeast China, and some local products are also transported to the mainland, thus strengthening the economic life of the local and inland areas and effectively promoting the development and development of ethnic minority areas in Northeast China.
