As The Richards began to look forward to the future, the global mathematics community suddenly erupted without warning!
The initial cause was Tao Xuanzhi publishing a letter from Qiao Yu on his blog.
It's quite common for successful mathematicians to frequently exchange emails discussing mathematical problems. The more adept the mathematician, the more frequent this occurs.
In fact, from an external perspective, both should have a shared language to some extent. For instance, they were both prodigies as children, and they didn't waste their talents as adults.
Especially since both of them have extensive engagement in mathematics.
Moreover, Tao Xuanzhi had highly praised Qiao Yu, who was not yet widely recognized in the world of mathematics, on more than one occasion.
It's evidence of this when he stood up for Qiao Yu multiple times, and it was expected that they would have private contact.
