Laiyang County in the early Ming Dynasty was a big county in Shandong Peninsula, including Laiyang, Haiyang, Laixi and Mu Ping today.

In the early Ming Dynasty, because of the war, the Central Plains was vast and sparsely populated, Laiyang was mountainous, the traffic was inconvenient, and it was less affected by the war, so there were also immigrants, but not many.
