Professional liners are people who wait in lines for others for things like concerts or movies in exchange for money. They typically work in cities, standing in lines on streets or outside shops. This type of work is most common in China, where the number of professional liners is growing. Their pay depends on the event they are lining up for, and they earn money by the hour. All they need to do the job is know the address for where the line will be; no other supplies or qualifications are required. While the work provides easy money, the document's author does not want to become a professional liner, as they instead want to go to university to become a lawyer.
