Positive discipline is an educational method with the core values of establishing positive relationship, cultivating sense of responsibility and self-discipline. There are several reasons for using positive discipline to educate children:

1. Enhance parent-child relationship: Positive discipline emphasizes establishing good communication and trust with children, which helps to enhance parent-child relationship and make children feel the care and support of their parents.

2. Cultivate children's self-esteem and self-confidence: positive discipline encourages respect for children's feelings, needs and opinions, and helps children build self-esteem and self-confidence, so as to better face challenges and difficulties.

3. Cultivate children's sense of responsibility and self-discipline: by setting clear rules and expectations, actively discipline and teach children to take responsibility and abide by these rules. This helps to cultivate their independence and problem-solving ability.

4. Reduce punishment and conflict: Positive discipline does not rely on punishment to correct behavior, but solves problems through guidance, communication and cooperation. This can reduce family conflicts and create a more harmonious family atmosphere.

5. Cultivate children's spirit of cooperation and empathy: positive discipline encourages children to cooperate with others and learn to respect and understand others' feelings. This helps to cultivate their social skills and interpersonal relationships.

In a word, active discipline can provide a caring, supportive and respectful environment for children's growth, and help them to give full play to their potential and become responsible, self-disciplined and empathetic adults.
