Visitor pattern decouples the data structure from the operations acting on the structure, making the operation set relatively free to evolve. Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia

Netease's film recorded another real death in a calm and depressing way. Under the camera, these dead people died without relatives. They were either strangers, people living alone, or elderly people living alone. Their death had no sadness, no tears, no funeral, and was as calm as if they had never been here. Those with relatives will be brought back by their relatives, while those without will be cremated and placed in a small iron box. The department responsible for reporting the iron box cleans up the iron box every 5 years, pours the ashes in the box into a large pit and buries them together with the iron box. Smoke floated and they left the place where they used to live quietly.

For example, when red, green and blue are all at a maximum of 255, mixing in Screen mode will result in white with RGB values of (255,255,255). On the contrary, black means 0. Therefore, mixing with black in this mode has no effect, while mixing with white gives the maximum RGB color white (RGB values are 255,255,255).
