Digital positive interventions (DPIs) are self-paced, interactive, customized interventions combining positive psychology interventions (PPIs) with positive technology. Many studies have proven the effectiveness of DPIs in improving well-being in the workplace. This paper proposes a novel digital positive intervention, the Mindful Tea-Drinking Practice (MTDP), based on a Chinese mindfulness App. It integrates Chinese tea culture and positive psychology theories and aims to enhance employees’ flourishing in the Chinese workplace. The MTDP comprises two components: the mindfulness App and the mindful tea. It utilizes the Elements Model to develop a 4-week, 10-minute daily mindful tea-drinking practice. This program is attuned to Chinese cultural contexts and person-activity fit in the Chinese workplace and reduces hedonic adaptation by using a variety of activities. It enhances participants' engagement, motivation, and adherence by using positive interactions, habituation, and personalization. It is highly scalable, easily accessible, user-friendly, and cost-effective. These features make it potentially appealing to a broad population and thus able to improve human flourishing significantly. Future studies and applications should address enhancing the effect sizes and adherence to DPIs and incorporating cutting-edge AI technologies to help more individuals live flourishing lives.
