The new generation mainly refers to the post-80 s and post-90 s, and they currently account for 60% of the 65.438+600 million migrant workers, about 65.438+600 million. They go to school after birth and go to work in the city after graduation. Relatively speaking, the new generation of migrant workers are not so familiar with agriculture, countryside, land and farmers. On the other hand, they are eager to enter and integrate into urban society, and we are not fully prepared to accept them in many aspects. The age of the new generation of migrant workers is 18 to 25 years old, showing the characteristics of "three highs and one low": high education level, high career expectations, high material and spiritual enjoyment requirements and low work tolerance.

Cenozoic (65 million years ago, Cenozoic) is the latest geological age in the history of the earth [1]. With the extinction of dinosaurs, Mesozoic ended and Cenozoic began. The Cenozoic is divided into three periods: Paleogene, Neogene and Quaternary. It includes seven eras: Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene and Holocene. The strata formed in this period are called Cenozoic. The Cenozoic era is characterized by the high prosperity of mammals and angiosperms. Because the biological world gradually presents a modern look, it is named the Cenozoic era, that is, the era of modern biology.
