The word "occupation" comes from the English word "career". According to the Oxford dictionary, the original meaning of "road" can be extended to a person's life path or progress path, emphasizing the responsibility given over time. Career covers the development process of one's life. It refers to a person's career experience or continuous work and employment process in his life, which is a dynamic development process that accompanies an individual's life. The predecessor of vocational education is vocational guidance. With the development of times and theories, career education has gradually surfaced and stepped onto the historical stage. 197 1 year, Dr. Mahlander, the director of the federal education agency of the United States, formally put forward the concept of "vocational education", which marked the beginning of the modern vocational education movement in the United States.
