From the perspective of communication and media studies, this article explores a comparison between the image of older adults presented on media and online self-representation facilitated by the use of smartphones. The qualitative textual analysis was conducted with a sample (228 posts, from 1 January to 31 December,2019) selected from a representative WeChat Public Account targeting at older adults in China. The results demonstrate that leisure and recreation is the most frequently mentioned topic (58%) with memories of past life receiving the least references (3%). The striking features of popular posts among older people include a highly emotional tone, bright colours and multimedia. Sentiment analyses shows 68.42%, 13.16% and 18.42% of positive, neutral and negative emotions, respectively. A generally positive attitude of self-representation is in a sharp contrast with the stigmatic media image of older adults. The article concludes that the visibility of Chinese older people may help to reduce the stigma surrounding old age in China.
