E-sports clubs are also called teams. Like clubs in sports leagues (such as NBA), it is a mutually beneficial organization where athletes get together. Professional teams generally have unique logos (such as team logos and uniforms) and unified schedules. With the standardization of the industry and the continuous improvement of the game level, there are more and more new roles in the professional team, such as team leader, coach, analyst, etc. They are generally responsible for the team's behind-the-scenes work, such as player guidance and game analysis.
