How the Hell would I know? They’re all just a bunch of gooks to me! J/k. Don’t report me to SJW Central Control please!
SHI: One should just go with a Vietnamese or Northern Chinese girl if you’re craving a Korean. Can’t tell the difference anyway.
SHI is a connoisseur of women, and I am more like a common sewer when it comes to women, but I will respect his judgement nevertheless.
Northern Chinese look very much like Koreans, and I very much doubt if there is a good way to sort them out. Koreans do have very prominent high cheekbones. That’s their Mongolian heritage as they pretty much came from Mongolia long ago. They along with the Japanese settled on the northeast coast of China in the Shandong area 7-8,000 years ago (believe it or not) and stayed there for many years. See recent excellent work by Martine Robeets on this.
The Koreans may have moved in from there 3-5,000 YBP, and Japanese invaded Japan in a huge wave 2,300 YBP. These people were called the Yayoi. The Yayoi are actually thought to have moved first from Shandong to Korea and then south from Korea to Japan a couple thousand years ago. But Northern Chinese and Mongolians are more or less the same thing.
The Japanese came from this same Mongolian stock, but they bred in so deeply with the Ainu that they definitely look different from Koreans. But they both also look quite similar, and it’s not easy to tell them apart either. In addition, there are a lot of mixed Japanese-Koreans in Japan. They’re almost a cliche.
Viets definitely look different from either Japanese or Koreans. They are also full of Chinese, but they are full of Cantonese Southern Chinese (“the barbarians” as the Northern Chinese refer to them), and Southern Chinese look a lot different from Northern Chinese.
Viets are a mixture of a more Austroloid type exemplified by the Montagnard tribesmen (look at a photo of them sometime). Actually the Montagnards are more like Australoids transitioning to Mongoloids or early SE Asians. Completed modern SE Asians are Mongoloids with some lingering traces of their Australoid heritage.
2,300 years ago, a huge wave of Southern Chinese conquerors spread through Vietnam and thoroughly bred in with the population. Nevertheless there was a Chinese minority in Vietnam in recent who tended to run the businesses (as usual). They were quite persecuted after the Communists took over, and most of them fled as boat people.
