Holding a farewell ceremony when the backbone teachers retire not only expresses the gratitude and blessing of the school, but also fully affirms the career of the old teachers. It is also an incentive for on-the-job teachers and has far-reaching significance for the school to inherit and carry forward the culture of respecting teachers and attaching importance to education.

In addition, backbone teachers generally have certain authority in a certain field, and the follow-up teaching research in this field needs the support of backbone teachers.
