有個長輩說，人生有四個階段: 你不知道你不知道，你知道你不知道，你不知道你知道，你知道你知道了！

請問要如何翻譯？

A senior had ever pointed out the four stages of life:1. you don’t know you don’t know,2. you know you don’t know,3. you don’t know you know, and4. you know you know.

Thank you!不用完成式嗎？

Chicho HuangI'd known you'd known.

Chicho Huang 你不知道你不知道 = You don't know you don't know.你知道你不知道 = You know you don't know.你不知道你知道 = You don't know you know.你知道你知道了 = You know you know.以上句子都省略了 that
