Take JD.COM Reading Festival in 2023 as an example. April 23rd is the annual World Reading Day, and the book promotion activities of JD.COM Reading Month last from April 3rd to April 23rd. There are six major brands, such as Beidou, Zheshao and Little Mammoth, with 50% discount and 300- 100 coupons superimposed. The actual discount is less than 30%.
