1. certificate is not universal: in China, the issuance and management of electrician certificates are the responsibility of local electric power management departments (such as State Grid Corporation or Electric Power Bureau), and the electric power management departments in different regions may have different provisions on the validity period, examination standards and audit standards of electrician certificates. Therefore, the electrician certificate you obtained in Hengyang Electric Power Bureau will not be recognized in Huaihua, and you need to obtain a local electrician certificate again.
2. Different regulations in different places: There may be differences in the regulations of electrician certificates by local power management departments, including examination contents, examination standards and audit standards. So even if the electrician's license you got in Hengyang Electric Power Bureau is valid, Huaihua's regulations are different and you can't get in.
