There are three main reasons for the surge in the number of secondary construction engineers in Hefei: with the determination of Hefei's grand blueprint for building a regional megacity, Hefei's economic development has entered a fast lane, and various construction projects have started one after another. Construction enterprises and related units are eager for professional and technical personnel, and the demand for talents is increasing, which leads to the growing number of textual research families year by year. In addition, after the adjustment of zoning last year, the former candidates from Chaohu City and Lujiang County entered the Hefei Examination Area, and the number of new candidates for the second-level constructor qualification examination this year is considerable. More importantly, the state's supervision in the field of building construction is increasingly strict and standardized, and holding certificates has become the knowledge of employees in the industry, and certificates have become an indispensable bargaining chip for employees' employment.
