In the deep-seated transformation of senior high school education catalysed by the reform of the college entrance examination, the function of career education in senior high school has garnered attention. This paper examines career education in senior high school through the lens of Bourdieu's theory of the field. It is not only significant for theoretical reconstruction but also for re-understanding of methodology. It highlights the necessity of viewing the propelling role of capital and power, particularly cultural capital, from a relational perspective within its structural context. In addition, the process is examined in terms of the significance of the distinct habits that shaped its construction and practical logic. The career field in senior high school emphasize ‘value leadership’ and ‘personal growth’, moulding field habits through the interplay of relationships within the field and interactions with other fields, such as the ‘college field’ and the ‘workplace field’. This interaction contributes to the development of field behaviours and stimulates the psychological field's growth and transformation. It aids actors in generating their patterns of practice, thereby attaining the dual objectives of intellectual and social construction and development.
