Northeast China–usually defined as the provinces of Liaoning, Jilin, and Heilongjiang–does not belong on your list. According to the 2000 Chinese census, about 10% of the population of Northeast China comes from ethnic minorities – the majority of whom are Manchus, but also including significant numbers of Mongols and Koreans. That is far from being 'one of the most ethnically "pure" populations in the world'-especially when compared to Japan or Korea.
Indeed, even though Northeast China was (in 2000) approximately 90% Han, prior to the 19th century Han were a minority in the region, and Manchus were the numerically (and politically) dominant ethnic group.
According to the 2000 Census, the most ethnically homogenous part of China is not the North or Northeast, but rather Eastern China, which is over 99% Han (and, as well as being over 99% Han overall, 4 of its 7 provinces are over 99% Han too.) By contrast, North China is about 94% Han and Northeast China is only around 90% Han.
(There have been two Chinese censuses since, in 2010 and 2020, but I can't find ethnicity figures for them.)
