The journey of solving a mathematical problem is as important as the solution itself, for it teaches us patience, persistence, and the joy of discovery.
解决数学问题的旅程和解决方案本身一样重要，因为它教会我们耐心、坚持和发现的快乐。
It must be remembered that while sympathy with joy intensifies the sum of joy in the world., sympathy with pain does not really diminish the amount of pain. It may make man better able to endure evil, but the evil remains.
真相还没穿上靴子，谎言已经跑遍全世界。
