How many times does the shutter in a SLR camera mean?

When buying a new machine, the number of shutter times indicates how many times the machine has been exposed, that is, whether it has been used. Generally, the shutter life of low-end cameras is about 654.38+ 10,000 times. Even if the life of the shutter ends, the shutter assembly can be replaced. I remember a photographer in Beijing introduced that it should be Nikon D200, and the replacement of the shutter assembly should not exceed 654.38+0000 yuan. The one upstairs is right. The average person (non-professional) has used it for 654.38+ ten thousand times. I'm afraid the machine has long been an antique, so the key is to look at the shutter times when buying a new machine to see if it has been used by others. As for the shutter life, don't worry.
