"One dou makes you poor, two dou makes you rich"? Is this long-standing saying true or false?

"One dou makes you poor, two dou makes you rich, three dou and four dou sells you like tofu..."

This is a common saying describing fingerprints.

I believe that many people were young

I've heard from the elders at home.

So

Why do people say this?

Is there any scientific basis for this statement?

Come and see

Do you understand after reading this?

Fingerprints are formed by uneven lines.

The protrusion is called the mastoid line

The concave part is called a small furrow

Fingerprints are divided into three categories according to their patterns and shapes.

They are "bow", "jib" and "dou" respectively.

In ancient times

Both bucket and dustpan are used to hold items.

Plus the lines on the bucket are in circles.

People think this is a way to make money

The lower end of the dustpan is open.

People think you'll make money.

It will also be scattered, and the money cannot be retained.

That’s why there’s a saying that the more fights, the better.

To have a good future

We should still work hard and down-to-earth!
