One of my classmates has leukemia, and we want to raise money for her treatment. Is there a better way? urgent

The most direct way is to initiate the whole school donation proposal. It is best to get strong support from school leaders to carry out this initiative inside and outside the school. Mobilizing teachers, students, parents and various social forces outside the school requires the support of local government departments such as civil affairs and women's federations, through which enterprises can be mobilized to donate money.
