Mathematics in technical colleges pays more attention to the cultivation of labor skills. After graduation, they have generally mastered the corresponding labor skills, and they can be competent for a certain job when they enter the society. All rural registered students with full-time status in technical colleges, non-agricultural registered students in counties and towns and students from urban low-income families can enjoy state grants. The subsidy standard is 1500 yuan per student per year, which is used to subsidize students' living expenses.
