^High school life^
In a certain math class, Lin Liuer had a "one-day deskmate" - Chang Yan, her idol.
She gradually discovered that this "great god" was different from what she had imagined.
The final exam for the first year of high school also became a "class placement test" from a certain perspective. Lin Liuer discovered that there was a strange but familiar name in her class - "Chang Yin".
"Does Chang Shen now have to use real names in class?"
Later, this "one-day deskmate" became "permanent".
(This is like a person who opened a one-day VIP and accidentally turned it into a permanent one)
She grew up in her new class in the second grade of high school, and bravely entered the world of mathematics under the leadership of her classmates...
"She's actually pretty smart."
In the end, Lin Liuer and Chang Yan were recommended to Qingbei through IMO (Mathematical Olympiad).
"Our high school is over."
Purpose: Describe the life of high school students and show the charm of mathematics
