Discounts. According to the inquiry about Haidilao's preferential policy, we learned that Haidilao has discounts for students. During the corresponding time period, consumption can be discounted at 30% or 12%. The discount is relatively large, and many students will eat Haidilao. Haidilao’s student discount is for the entire order, so it includes the bottom of the pot. Haidilao student discount time limit: Monday to Friday 15:00-17:00, 22:00-23:59, weekends 21:00-23:59, 00:00-7:00, 31% off.
