说明：  球场在线售票系统。具体分为两个座位区:红色座位区供公众通过本系统订票;非红色区域，可通过热线进行私人预订。 在该系统中，根据客户对该票务系统的忠诚度(累计积分)，将所有客户分成从1到7的7个优先级(号码)。优先级数越小，优先级越高。由一个客户组成的所有票务流程(购买/取消)都被赋予该客户相同的优先级编号。
(Online ticketing system for courses. There are two seating areas: the red seating area is for the public to book tickets through the system; Non-red areas, private reservations can be made via the hotline. In this system, all customers are divided into seven priorities (Numbers) from 1 to 7 based on their loyalty to the ticketing system (accumulated points). The smaller the priority, the higher the priority. All ticketing processes (purchase/cancel) consisting of a customer are assigned the same priority number to that customer.)
