Recently, the 15th Beijing International Film Festival Short Video Unit Theme Forum and Honor Ceremony were successfully held at the Communication University of China. The short video section of this year's film festival is themed "Discovering Beauty and Transmitting Value", focusing on creative expression under the pulse of the times, and gathering more than 6300 excellent works from more than 30 countries and regions around the world. The vlog series of short videos titled "Twenty is Not Confused, Thirty is Just Seventy" produced by the Guangzhou Civil Affairs Bureau and Guangzhou Radio and Television Station for the 8th Guangzhou Old Expo was awarded the second prize in the "Civil Affairs China" section of the 15th Beijing International Film Festival.

This film tells the story of a cross generational "soul exchange adventure": a grandmother born in the 1950s accidentally "travels" to the body of her granddaughter born in the 2000s, and is forced to take over the task of visiting the Guangzhou Elderly Expo as a young newcomer in the workplace. At the 8th China (Guangzhou) International Elderly Care and Health Industry Expo (referred to as "Guangzhou Elderly Expo"), she uses her granddaughter's physical experience to participate in activities such as elderly care products and physical examinations, which not only creates a comical cultural generation gap, but also unexpectedly injects a fresh silver hair perspective into the elderly care industry, using a novel perspective to express the psychological needs of the elderly and focusing on the "silver hair economy".

The entire film wraps around social observations in the form of light comedy, deconstructing the imaginative anxiety of young people towards aging and reflecting the assistance of technology in facilitating elderly care through the collision of intergenerational experiences. This dialogue that transcends time and space reflects the need to pay attention to the elderly who are not good at using technology products while technology is rapidly developing. The entire film is characterized by light comedy and centered around humanistic care, showcasing the understanding and coexistence of the generation gap between the elderly and young through novel perspectives, providing a warm footnote to contemporary workplace and aging issues.
