I'm actually more concerned about Chinese mathematics.

Once Chen Luyu asked Fields Medal winner Shing-Tung Yau a question: 1234 is equal to 0, 1027 is equal to 1, 1069 is equal to 3, and 8609 is equal to 5. What is 2471 equal to?

Shing-Tung Yau was a little embarrassed: I can't answer this right now.

Chen Luyu turned around and asked a kid: What is it?

The kid: There is one circle in 1027, then there are three circles in 1069, there are five circles in 8609, and there is no circle in 2471, so 2471 is zero.
Shing-Tung Yau once again showed an awkward yet polite smile: Very good, very good, very good.

Clever kid

It's an interesting question technically:

Skywatcher's Problem:
What is the asymptotic behavior and distribution of the number of integers with a fixed number of "circles" defined above?

Possible thesis for elementary students:
On the long time evolution of dynamics of the number of circles among large integers.

Chen Luyu：Really? I don't believe you.

You have zero understanding of modern mathematics period.
