There is no doubt that today's "book-throwing war" borrowed the saying that "Hermione collects books in the British subway". From the fermentation time of Hermione's book collection in the British subway, to the data preparation of the "book-losing war" in the New World, to the collection of lost stars, and then to the negotiation with cooperative publishing houses, it can be inferred that the New World decided to do it in China at the first time, and quickly invested manpower and material resources to prepare for this activity. During this period, the New World mainly did the following things: get in touch with cordelia Oxley, the head of London Underground Reading Action, who Emma participated in, and get her support; Invite influential friends, publishing houses and public transport service providers in all fields to make all this possible together; A special website and online system have been developed for the "Battle of Lost Books".
