Dark-time

说明：  暗时间就是可以归自己暗中随意支配的业余时间，既可以用来进行思维的时间，也就是没有产生直接成果的时间。比如说，看书并记住书中的东西只是记忆，并没有涉及推理，只有靠推理才能深入理解一个事物，看到别人看不到的地方，一个人走路、买菜、洗脸洗手、坐公车、逛街、出游、吃饭、睡觉，所有这些时间都可以成为“暗时间”，你可以充分利用这些时间进行思考，让你的认识能够脱离照本宣科的层面，从而进行发现和创新。
(Dark time can be attributed to the own secret disposal spare time, both can be used to thinking of the time, which is a direct result of the time did not produce. For example, read a book and remember something of the book is just a memory, and does not involve reasoning, in-depth understanding of a thing only by inference to see other people do not see the place, a person walking, grocery shopping, wash your face, wash your hands, take a bus , shopping, traveling, eating, sleeping, these all the time can be a " dark time" , you can take full advantage of these time to think, let your understanding from the scripted level, discovery and innovation.)
