In recent years, quite few of youth films have made good box office performance. With close study it could be revealed that by meticulously choosing the narrator, applying ocularisation and anachronies, presenting sounds and scenes with time features, youth films generally possess narrative strategies which meet the physiological needs of the mainstream audience, especially those audiences born after 1980 and 1990s. That is an important reason for the popularity of youth films. Nevertheless, youth films are harshly criticized for their increasingly stereotyped narrative strategy and it will inevitably make the audience end up in aesthetic weariness. So, to maintain the audience's enthusiasm, youth films should have their narrative pattern diversified, and the focus should be expanded to cover youth of different ages and different types of people. At the end of 2017, the film Youth attracted audiences born in 1950s and 1960s,by setting its background from 1960s to 1980s, although it has not completely jumped out of the narrative pattern of previous youth films. In 2018, Forever Young finally presented a new narrative pattern of the youth film by exploring the meaning of youth in different ages, and so expanded its circle of audience to people of several generations, and realized the transcendency of the narrative strategy of youth films.
