The period for intervention was 14 weeks, including 2-week quiting preparation intervention and 12-week postquit intervention. The number of messages/pictures/audios received by participants will gradually decrease (will be intensively sent to them during 2-week prequit and 4-week postquit, and less intensively during 5-week to 12-week postquit), and follow-up questionnaires were sent only once a month in 14-28 weeks (week 16, 20, and 26 after the quit date). A WeChat group was created for answering questions from participants, and sharing the latest resources related to quitting smoking, and promoting communication between participants.
