In today's society, work is overwhelming and people are increasingly scrambling for time. More people are working on how to use time effectively and rationally, including scientific learning methods, speed reading and shorthand, and memory curves. In addition, there are some people who are committed to ways to relieve unbearable stress, such as yoga, SPA, DIY, clubs, etc. In a series of time studies, there is a group of people who are committed to the study of sleep time. The basis of the concept is: people only work for 8 hours a day, but sleep time often exceeds 8 hours, accounting for one-third of a person's life. If it can be used effectively and reasonably. It is equivalent to double the value of life. Among this school of "sleep creates value" theory, one school is called the "hand of the dream god".
