The second-level cost engineer refers to a professional engaged in cost management and budgeting in the field of construction engineering. The construction industry has been in a state of rapid development and high demand, and there is a great demand for secondary cost engineers with cost management skills. They play an important role in project budget, cost control, bidding and so on, and can get higher wages and rewards. Psychological counselors refer to professionals engaged in mental health consultation and treatment. Although the demand in the field of mental health is increasing, the income of psychological counselors is relatively low. Psychological counselors need professional training and relevant qualifications, and at the same time, it takes some time and energy to establish word-of-mouth and customer base. Therefore, due to the high demand and high salary level in the construction industry, it is relatively easier for secondary cost engineers to obtain higher income.
