In the era of big data, the bag for traveling has become smaller and more accurate. For example, when it comes to survival in the wilderness, the weight of equipment from tents, sleeping bags and walking tools to water bottles, food and beverages can be accurate to the extent of grams. Therefore, a school teacher in Henan ten words in the resignation letter: the world is so big, I want to go and see. Because out of the travel, can all just take a bank card, relevant documents and communication tools can be, the bag can be as small as a palm-sized handbag.

However, the traditional travel bag for survival or travel, it seems that there will indeed be "the bag has been prepared, to start a new journey. The road is long, check the bag will find that some things quickly used, some can not be used for the time being, some want to use but have not prepared, and some will be accompanied by us to the faraway place ...... " phenomenon. The moral of this material makes me think of today's students, they are about to start the journey of life, what are prepared in the "bag"?

This is a seemingly philosophical proposition. Material preparation depends on the necessity of survival, where to go in what environment to survive, become a prerequisite. Or rather, what to bring for what purpose depends on the necessity of survival. There is a question here of subjective intention versus objective reality. Just like choosing a subject in school, at the beginning, you think very well, such as choosing engineering to be an engineer in the future, choosing science to be able to make a difference in the field of natural sciences, and liberal arts to adapt to a wider range of areas, etc., which are all subjective ideas. However, after graduation to society, some cases are not able to realize the desire to engage in their own major, engineering to do management, some teacher training students failed to become a teacher, but became an official, Peking University, a student later sold pork, and so on.

We have to adapt to the survival environment, the same in order to prepare for the journey of life, that is to say, to put things in the bag, are in order to adapt to the survival of the preparation. However, what is learned may not be used, and even in order to survive the need to learn while working, and even some of the things learned to old age is not useful ...... Therefore, in today's era of big data, this is a pseudo-proposition.

The arrival of the information age has solved a lot of blind decision-making, just like the liberalization of the two-child birth policy, which will inevitably lead to a shortage of pediatric health care workers, which does not need big data statistics, according to the social tendency can be judged. Of course, the role of data is to provide a more accurate scientific basis. Then again, Ma Yun Ma Huateng subverted the marketing profession and refreshed the consumer market with new ideas. So do we still have to say: in the traveling bag prepared a lot of things, but did not use. Who is filling our children's traveling bags and what are they filled with?

Seeing this title, I also thought of "There is more to life than what is in front of us, there are poems and distant fields." This is the title line of a self-published media. This quote has something to do with the traveling bag, yet it is not material, but spiritual. In today's "nothing can't be done, only can't be thought of", the resigned female teacher to "go to see" the big world, to shake off those bags "what is useful and what is not useful" entanglement, whether in the spiritual bag, ready to go to the field. Spiritual bag, ready to accept the "poetry and faraway" rich world fully prepared?
