In Japan, there is a traditional culture of calligraphy that expresses the beauty of the Japanese character. In the Japanese education system, all elementary school students learn and practice this culture in classes. Most of the case, we choose words that have a positive meaning, such as goals, gratitude, or dreams, and write them with a brush on traditional Japanese paper.
The picture below was written by a child of our colleague, which means "gratitude" in Japanese. If you are interested in culture, you should give it a try.
