Shangri-La was a concept that often appeared in novels, poems, and movies. It referred to a place that was isolated from the outside world. The scenery was beautiful, and the people lived simple and happy lives. In novels, Shangri-La was often an idealized place. Compared with the noise and pollution of the real world, it seemed peaceful and beautiful. The way Shangri-La is realized may vary from novel to novel, but it usually needs to meet some specific conditions such as superior environment, inconvenient transportation, political stability, etc. In literature, Shangri-La was often described as a place free from war, disease, poverty, and pain, where people lived a leisurely life. In movies and television works, Shangri-La was often depicted as a world without worries and troubles, where people pursued true happiness. In real life, the concept of Shangri-La was not defined. It could be an idealized place or a different social system or ecological environment from the real world. No matter what, people have been exploring how to create a better future, hoping to realize a true paradise.
