There is no need to print a handwritten commitment letter for the examination registration of public institutions. According to the relevant information, the registration materials such as the commitment letter of no criminal record and the commitment letter of job avoidance must be signed by hand. Take a photo or scan after signing. The examination of public institutions is also called the examination of career establishment. This work is entrusted by the personnel department of each employer to the personnel examination center affiliated to the personnel department of the province or prefecture-level city (institutions and examination centers put forward and organize registration, examination and submission of the results list of the employer, and some units organize the implementation of the proposition by themselves).
