数学的语言是普遍的，超越了文化和语言的障碍。
The language of mathematics is universal, transcending cultural and linguistic barriers.
Stories you read when you're the right age never quite leave you. You may forget who wrote them or what the story was called. Sometimes you'll forget precisely what happened, but if a story touches you it will stay with you, haunting the places in your mind that you rarely ever visit.
要有继续追逐梦想的勇气。
当准备遇到机会时，成功就会到来。
