Please speak that sub in the eventual video.

Hm.

Jaime.

Oh, today we're going to talk about DNA tests and specifically ancestry tests.

Because if you're East Asian background and you've ever taken a test with big companies in the West to like ancestry or 23 we'd you've probably found that the results can be a little lacking.

Yeah.

Yeah.

E did this DNA test, like, three years ago with ancestry.

And when I got back the results, it said that I was 99% East Asian and 1% Pacific Islander.

That's very apparent.

Looking at a place, I guess.

Right.

So it was like $100 wasted.

So for someone to tell me that I'm basically an Asian So I did the test myself a couple years ago with my heritage, and I got 94.4% Chinese and Vietnamese.

That means they didn't split it out.

And I got 4% Japanese and are Korean, and for some reason, inexplicably, 1.6% finish.

So that is quite unsatisfying for me.

I wanted to know where my family's from.

I'm pretty sure my family is mostly Chinese.

but I wanted to know which part.

And so to get this sort of like a big lump off East Asia is highly unsatisfying to me.

So why is this happening?

Is essentially a database problem, Since companies can only match your DNA with the DNA samples they have collected, the results are limited by the pool of people they have.

So if you're in the United States, you're not likely to have a whole lot of specific information about someone in China.

But that's why a whole bunch of Chinese DNA test companies have popped up in recent years.

Companies like 23 Wilfong and We Jean promise more specific results down to which part of China your ancestors air from based on their pool of Chinese people's DNA.

So we wanted to try it for ourselves because we both had questions about where our families came from.

That means a lot to someone like me, because on my dad's side, my dad is haka, and that means that supposedly there was a big migration from north to South in the Jin Dynasty.

How long ago was that?

More than 1600 years ago.

Okay, so big migration and my dad's side of the family doesn't have any records about where they come from or who they are.

And I'm just curious.

I've been curious my whole life.

So he spat in unholy amount of spit into a tube.

Who's gonna look?

Oil packed it in an envelope.

All right on that should be it.

And shift our spit to 23 more Fong headquarters in Chengdu.

Our results came back three weeks later.

So let's see what they say about my Chinese ancestry.

I am apparently 81.73% Southern Han, 11.4% strong or die.

Okay.

And where's that from?

Its two of the ethnicities in Yunan province, which borders Vietnam and Myanmar and Laos.

Okay.

And I am apparently 6.87% Korean.

E got Korean.

So let me tell you about my results.

I'm 88% Southern Han Chinese, also 11% Korean.

I don't know if the percentage is actually means say that I'm, like, actually 6.87% Korean.

Just that 6.87% of my DNA matches someone who also said they were Korean, and that's sort of one of the flaws of these DNA tests.

It's based on someone saying that they were of this ethnicity.

And what's more, because companies often don't share the same samples, the results can vary from service to service.

And just to illustrate how widely varying the data is, I sent my DNA toe.

Another Chinese DNA testing company called We Jean.

They gave me very different ancestry results.

They said I was 57.26% Southern Han Chinese and 26.1% Northern on Chinese.

The other thing is that these results are based on how big the sample sizes.

So if it's very small like, say, a couple 100 or 1000 people, you might get very unsatisfying results.

We talked to a genetics professor at the University of Hong Kong about the sample size issue, and this is what he said to get really good coverage, you may need millions off people to kind of have a what we call it statistical power to discern, like differences between North and south of China and the CEO of 23 Wilfong thinks that's possible.

It's India you teaching was fine in this region.

May water Harling, young train your sense of, uh, Jimmy has a whole swath pulling your bunion to Schuessel.

Angelina, don't go that are reaching it.

Sure.

This whole girl don't You can call us, That's why.

So what about the way that sort of challenge and as the sample sizes of these companies grow, way could actually see our results changing.

Most importantly, have you told your parents?

I did, but they didn't really give me much of a reaction.

They're just sort of like, Okay, this is what, like, one company says about what they think we are, but we know who we are.

And we know, like, our family history.

And so what does it matter what our ancestry is?

Well, you know, like, what?

Our family is fair enough.

Well, my family is different.

I think we don't know as closely where we've come from.

So they were curious as well, and, uh, they just know that were most probably not finish our Korean.

Um, but when I explain it to them, they said, Yeah, you know, it kind of checks out that the haka thing, you know, going all over the place.

Yeah, that's that's how they processed it.

and they were.

They were quite amused, actually.

But then at the end of the day, it's really just about whether our DNA matches someone who reported what they are.

Trust me.

When I explained that to them, they lost interest immediately.

E I guess it's sort of like a horoscope.

You can always just take it or leave it.

We want to hear your DNA stories, too.

So if you've taken any one of these tests, tell us about it.

And, as always, subscribe to go threat to Hello.

Hello.

I was wondering what you thought about us being 1.6% and more.

Aren't you surprised?

No way.

It has to be a Chinese or Japanese or called in white e Just wanted to know your feelings about this E um mhm.
