| Based on the theory of weak relationships, this study employs a mixed-methods approach combining literature review, semi-structured interviews, and participatory observation to examine the formation, maintenance, evolution, and distinctive characteristics of weak relationships in "dazi socializing" among young people. Findings indicate that during the online matching phase, shared interests and hobbies serve as primary determinants, with certain connections capable of developing into intimate relationships. Established "dazi" relationships are subject to various constraints, exhibit diverse evolutionary trajectories, and prompt multifaceted coping strategies among youth. These weak relationships are characterized by low frequency , strong goal orientation, low emotional intensity, clear boundaries of intimacy and relative distance, and targeted reciprocal exchanges. The study further proposes optimization strategies for digital platforms concerning matching algorithms, creating community atmosphere, and ensuring security. |
