Cultural shock from loud public phone use and lack of headphone etiquette on Chinese public transport

Summary

Foreign travelers in China are often shocked by the widespread habit of playing videos, games, and taking calls on speakerphone at full volume in public spaces like trains, metro, and restaurants. This cultural norm is rarely challenged by locals, making it a persistent source of frustration for foreigners who value quiet public behavior. The lack of social enforcement and the expectation that travelers must simply tolerate or use noise-cancelling headphones creates a stressful and uncomfortable experience. Existing travel guides do not prepare visitors for this, and no practical solution exists to address the cultural gap.
