Thanks, I heard about Made with Lau a couple months ago when I happened upon some of their cooking videos on YouTube. 

Zhang Xizhe just looks vaguely southern-shifted Han to me. He also has this round partial double eyelid eye shape I associate with "Central China" Han and some more cosmopolitan-looking Beijing types- basically what I imagine many people in the CHB reference population look like based on how "northern"/"southern" they are genetically. He doesn't look distinctly Lingnan the way Joshua Wong does.



Joshua Wong on the other hand has a more distinctive Lingnan-Fujian eye shape where the eyes take up a larger portion of the face despite having monolids. He also has a "heat-adapted" smaller face and a lower hung nose with slightly wider nostrils, which is a SEA trait that's more common in Lingnan and Fujian than in the Yangtze Basin. These definitely aren't "deviant" or abnormal traits for that region of China.





Way to throw us poors/descendants of starving peasants under the bus for having "low facial harmony/symmetry"  His dad just looks Guangdong/Fujian to me, which is what you'd expect if his family has Teochew roots like MNOPS once said.

I really don't think Joshua Wong looks distinctively Lingnan. He can definitely pass in places like Hunan, Hubei, Fujian, and maybe Zhejiang. I think he and Zhang Xizhe share a lot of similarities: both have a similar face shape, and both have eyes set rather far apart, and both also have rather wide nostrils. I tend to associate such features with Central Chinese and not with SE Asians. I think the Guangdong athletes He Chong and Feng Junyan have a more overt southern pheno that is more similar to SE Asians.

It's possible that he has Teochew or Hokkien roots like you said, which are actually quite common in HK. I just don't think he looks typically Canto.

From my observations, it really isn't "peasants" or poverty itself that results in "low facial harmony", but rather specifically some people in rapidly industrializing environments. Actual peasants, nomads, and hunter-gatherers tend to have good facial harmony.

Alright I gathered an albumn of wanted Guangxi criminals, mostly from west/south Guangxi and most are of Han descent. Some of my immediate thoughts.

1. There is a distinct Guangxi look; this distinct eye area, this distinct cheekbone shape and in general many do diverge a lot from plains Han.
2. Guangxi is probably smaller faced than bulk Chinese Han, but their "facial growth" is not low. Their chin/jaw generally takes up more of their face, with a smaller/shorter midface.
3. Some amount of people here have low facial harmony compared to e.g Canto Abcs. I suspect their poor facial harmony is caused by poor nutrition/lifestyle as children.
4. Most criminals are facially more grown and robust than say top HS students due to lifestyle divergence; the former oftentimes do physical work as kids while the later oftentimes lead some extreme sedentary stunted lifestyle.
5. Guangxi seems to share structural continuitiy with Khmers and Austroasiatic. Some amount look South Asian shifted.

Random- but do you think that millennial PRC chinese (eg. your generation) had a higher rate of overgrown/robust looking people than other generations? 

My observation is that in northern chinese, elderly people are often long/narrow faced, gen X becomes wider, and then millennials are often wide (almost "ogre" ish at times), but then zoomers/Gen Alpha decreasing in face size again. ABCs of northern chinese descent tend to be smaller faced (but interestingly, 1.5gens often larger faced). 

Interestingly, a similar pattern might hold for eastern Chinese, with the exception that elderly eastern Chinese can be rather broad/square-faced for some reason (perhaps somewhat similar to Korean/Japanese elderly). Unlike the northern chinese pattern, where ABCs and elderly seem to overlap in facial type, eastern Chinese ABCs can often be narrow/small faced compared to their elderly. This may suggest some differences between northern and eastern Chinese elderly in terms of nutrition/lifestyle which does not occur in ABCs

My observations are different from yours. I think the older generations of Northern Chinese are quite robust, I've seen quite a lot of robust elders in Beijing, and most Beijingers (especially the older generations) can trace their ancestry to nearby Northern Chinese provinces such as Hebei, Shanxi, or Shandong. My maternal grandparents were both from small villages in Hebei, and they both looked quite robust to me.

However, the younger generations of urban Northern Chinese are less robust, either because of a change in diet or because of admixtures with Central or Southern Chinese.

I'm not that experienced with Eastern Chinese, but from my limited exposure to them I think they also follow the general pattern that I described and aren't that different from Northern Chinese.
