The pattern on the mask can convey a lot of information. For example, some masks worn by medical staff will be printed with slogans to boost morale, some will be printed with trademarks or brand logos to express brand loyalty, and some will be printed with animals, plants or other patterns to convey personality and show hobbies.
The pattern on the mask also reflects the specific culture and tradition. For example, in some countries, flower patterns are common because flowers have special significance in local culture. In other places, animal-related patterns may be more popular because they can show the local characteristics of the area. In a word, the pattern in the mask is not only decoration, but also has many meanings and cultural significance behind it.
