求一句中文的翻译（中译英）

Life is a mystery. You know how it began but have no idea if the ending is a tragedy or happiness.

life is just like a maze, You get in knowing it is beginning but you are never sure if we get out knowing it is a happy ending or just another misfortune.

"Life is like Mi Ju, see the beginning to the end I do not know is bad luck or happiness,"

life is just like a maze,whaching the beginning without knowing the whether results is misfortune or happiness
