This is a one-handed authentication. Single recruit requires uploading a single recruit admission confirmation and ID card with clear content, and the candidate's image is clear. Single admission confirmation can be printed and handwritten, but the text content of the module cannot be changed. Candidates' name, candidate number, ID number, signature and contact number must be filled in. If the content of the uploaded photos is unclear, the uploaded photos do not meet the requirements, and the information cannot be confirmed, which will affect the admission of single strokes, and the consequences will be borne by the candidates themselves.
