Traditionally, designers were merely limited to a single field to deal with their own work. Nowadays, they are not just a person who is good at design, but a person who lives with the concept of design. This is the attitude every designer should have towards design. What is highly challenging for every designer is that he or she must distinguish their works from those made in the past and that their design works are required to reflect the multiple ideological connotation in a direct and concise language so as to express different ideas. The more you know about, the more creative you will be. Therefore, designers are required to learn to remove what's unnecessary. But currently in design, the originally most real and simple part has gradually disappeared, which is the most terrible for us.
