The thoughts of those in power are often not as complex as they seem.
Take Tian Yan for example. Today, he initially just planned to meet Qiao Yu, to see this child himself. He didn't have the intention for him to join Yanbei University next semester, nor the intention to directly take him as a closed-door disciple.
Although Qiao Yu is indeed outstanding, at Tian Yan's age, observing more seems to do no harm.
What changed his mind were Qiao Yu's daily journal entries.
Solving equations is nothing special, gaining insights from solving them is nothing special, even tutoring juniors is nothing special, but directly discovering the beauty of mathematics and having personal interpretations of competition problems is quite rare.
In Tian Yan's mathematical career, he has encountered very few who talked about the beauty in mathematics, and without exception, these people have become prominent figures in the world of mathematics.
