The 11.16 event happened in Bijie City has raised much social concerns on homeless children in urban areas. Even though vagrant people in urban areas rescuing systems have been already established before，homeless people are often hurt and even dead without rescuing. It indicates that our rescuing management systems are not perfect. So this research systematically studies their living conditions，and analyzes the reasons why they are aggressively begging and organized begging and how to deal with these problems. Rethinking the defectives of rescuing management systems is not only meaningful for rescuing homeless people in cities，but also significant for maintaining the cities in good order and constructing harmonious society.
