Rule of 7 in research. You can find out anything if you are willing to go seven levels. If the first source you ask doesn’t know, ask them who you should ask next, and so on down the line. If you are willing to go to the 7th source, you’ll almost always get your answer.
真相很少是纯粹的,也从来不是简单的。
我是一个喜欢脱颖而出的人。
