Yidong
An intelligent student who you think studies all day, but is actually a gamer who likes to spend his free time gaming. You would think asking him for answers is a great idea, but when it comes to explaining the concept, he struggles.
Have you asked Yidong for the math homework answers?
I did, but I couldn't understand how Yidong got those answers.
