Was there a big earthquake in Laizhou, Shandong Province before?

No, there was a great disaster in the history of Jiaodong, which happened in the second year of Hongwu in the Ming Dynasty. I can't remember, either 1562 or 1652. Generally speaking, in this era, earthquakes occurred in the Bohai Sea and the Yellow River offshore, which triggered a tsunami and flooded the entire peninsula. After the water was spilled, it was deserted. So at that time, the court ordered immigrants from Yunnan, Sichuan and Shanxi.
