Is time more important than health? To promote the drawbacks of staying up late, a campaign with four activities will be held. (1) A performance art. Four helpers line up straight on the Li Promenade, and each hold a banner stating, "I stay up late, so I think slowly", "I stay up late, so I doze off in class", "I stay up late, so my weight keeps gaining", and "I stay up late, so I am not beautiful enough" to attract people’s attention. Then, they fall down one by one. (2) Promotion. Helpers distribute leaflets to students and passers-by. (3) A free medical consultation simulation. A "Chinese medicine practitioner" offers a free "medical consultation" to a patient, who is asked whether she stayed up late on bed. Then, the "Chinese medicine practitioner" educates the patients the drawbacks of staying up late, and at the same time give her a drink and a "prescription". (4) A post-interview. Helpers interview the patient and ask for her reflection after understanding the drawbacks of staying up late. Staying up late seems to help us earn a lot of time, but actually it also shortens our lives. Is it worth?
