Sheng Chuyi tossed her an Olympic Mathematics textbook, "The examples and explanations for the last three problems are on pages 132, 145, and 154. Read those first, and if you still don't understand, then you can ask me."
"Got it!" Shen Zhaozhao pouted, took the book, and flipped to the pages he had mentioned, indeed finding similar problem types.
The textbook in her hands, known as the "ceiling" of the Olympic Mathematics world, was infamously difficult just by the name alone.
