Why do you feel that many Japanese people look like Shandong people in Liaoning?

There is a simple reason. Both Japan (descendants of our Shandong people who migrated eastward to the Japanese archipelago to escape the war in ancient times) and Liaoning (descendants of our Shandong people who migrated to the three northeastern provinces to start a new life after the Republic of China 10) are descendants of our Shandong people, so the Japanese are especially like our Shandong people and Liaoning people.
