What certificate does photography major need to take?

National professional standard for photographers, who can obtain grade certification through grade examination. National standards are divided into five levels: junior photographer, junior photographer, intermediate photographer and senior photographer. \x0d\ In the past, you had to take the primary exam, but now it seems that you can take the intermediate exam directly, and you can take the advanced certification only five years after taking the intermediate exam. Generally, the intermediate level examination is mainly advanced certification, but advanced certification and above are not so easy, the number of places is too small, and there is an age limit. \x0d\ It seems that junior photographers must be 25 years old, intermediate photographers must be 35 years old and senior photographers must be 46 years old. (I don't remember clearly) \x0d\ The photography industry is talking about the photo level, and certificates are actually used less. Ordinary film and television, news media, art galleries, contract photographers and other photography professionals can see the standard at a glance, and don't care much about whether you have a certificate or not.
