What is Mr. XXX's mutual encouragement consciousness in his calligraphy works?

When writing encouraging words for Mr. So-and-so, the author often expresses by the way that he wants to do that, so he is encouraged by Mr. So-and-so. It means * * * learning and encouraging each other to make progress. For example, when writing works such as "study hard and make progress every day", "The sword front comes from sharpening, and the plum blossom fragrance comes from bitter cold", you can write the words "encourage with others".
