1 Authentication You can choose any of the three options, but it is best to choose the one with the certificate. For example:

Academic information: for example, English major of Peking University;

Professional information: such as engineers and teachers in IT industry;

Other information: such as the winners of the photo contest and the holders of professional certificates of photography;

2 Identity Description Just fill in your own identity information directly. For example, what you want to authenticate is professional information.

You are an industrial engineer by occupation, so you can fill in the description of the industrial engineer, and you don't need to fill in the rest.

Please ask questions if you have any questions. I hope I can help you!
