Why is there no watermark in the graduate application registration form downloaded from China Railway Talent Recruitment Network?

Allow download. Watermark now refers to the translucent logo and icon added to the picture to prevent others from stealing the picture. The graduate registration form downloaded by China Railway Talent Recruitment Network is allowed to be downloaded, so there is no watermark. Graduates' registration forms downloaded and printed from China Railway Talent Recruitment Network must be printed on both sides and signed by myself.
