The pre-sale ticket refers to the electronic ticket purchased in advance through the website or other third-party ticketing websites. This kind of advance ticket is usually cheaper than the on-site ticket, which can avoid the trouble of queuing to buy tickets on the spot. Sales of pre-sale tickets generally stop before the exhibition starts, which means that they can only be purchased during the pre-sale period. The advantage of pre-sale tickets is that the time and mode of participation can be determined in advance, avoiding the time and uncertainty of waiting in line at the scene. Moreover, advance tickets can also enjoy some additional benefits, such as limited participation in special activities such as surrounding commodities and autograph sessions.
