ELI5: Explain Like I'm 5

Su Zhaozheng

Okay, so imagine you went to a new school and you don't know anyone there. One day, you meet a really nice kid named Su Zhaozheng. Su is really good at math and helps you understand the numbers better. They're also really kind and always make sure you feel included when you play games at recess.

Su Zhaozheng is actually a real person, but they're not in your school - they're a historical figure from China. Back when Su was alive, they were known for their intelligence and for helping others. People like Su who are really smart are sometimes called "geniuses."

Nowadays, even though Su Zhaozheng is no longer alive, people still admire their intelligence and kindness. They think of Su as a role model for being smart, helpful, and caring towards others.
