It's best to make color pages with thicker paper. Write a history of your calligraphy. For example, when you were seven years old, you began to learn calligraphy, first from Yan Liu and then from Han Li. What style are you good at? In addition, list all the awards you have won over the years. Do more of your work.
Calligraphy specialty students mainly rely on exams and on-site writing works to select the best candidates.
