Why did Zhu Yuanzhang send Chang Yuchun to wipe out Shandong in Hongwunian of Ming Dynasty?

There was a massacre, and the Ming Dynasty was Anhui Ming Dynasty Group! Not one of our own anyway. Modern people certainly deny the massacre! If it weren't for killing Zhao in the battle of Changping! Modern people will still deny this history. Because it's not one of us! Those who are alive are all our own. The victim has no offspring! Not just Zhu Yuanzhang. Judy Yan's army killed a lot! But it should be the first time to immigrate.

There was nothing about northerners throughout the Ming Dynasty. Just look at the history books!
