How do you understand the Lost Generation?

The "Lost Generation" by Ernest Hemmingway referred to the young people in the United States in the 1920s. They lived in a turbulent period and were confused and lost in the face of political, economic, cultural and other factors. This group of people lacked clear life goals and values, and were easily influenced and manipulated by the outside world. They lacked a sense of self-identity and belonging. They have a wide range of interests and pursuits, like to explore new things and try different ways of life, but at the same time, they feel empty and confused, unable to find what they really want to do. In his novel, Ernest Ernest depicted the image of this group, and through their experiences and feelings, he reflected the various problems and contradictions of American society at that time. At the same time, this group was also one of the sources of inspiration for Ernest's creation. Through his novels, he portrayed their confusion, struggle, and pursuit, showing a true and unique image of the times.
