学校心育节可以用 "School Heart-nurturing Day" 或 "School Heart Education Day" 来表示。这个节日的来源可能是由学校和当地社区组织共同创建的，旨在通过一系列的活动和互动来促进学生的心理健康和人际关系的建立。例句：

Our school is hosting a Heart Education Day next week. We will have guest speakers, workshops, and activities to help students learn about healthy relationships and self-care.

I'm really looking forward to Heart-nurturing Day at school. I heard there will be a lot of fun games and activities that help us learn how to be kind to others and take care of ourselves.

I think Heart Education Day is a great idea. It's important for students to learn about healthy relationships and emotional well-being, and this is a fun and engaging way to do it.
