计算的目的是洞察，而不是数字。

The story you are about to read is a work of fiction. The names, characters, places, and incidents are either the product of the author's imagination or are used fictitiously. Any resemblance to actual persons, living or dead, events, or locales is entirely coincidental.

The best detectives are the ones who never stop asking questions.

每件事都是一个学习的过程：每次跌倒，都是在教你下次如何站起来。
