What are the applications of traditional Chinese characters in hard pen calligraphy?

Look up the dictionary when you write, and don't make mistakes, such as:

Dry: corresponding to three traditional Chinese characters: (dry) involved, (dry) dry, (dry) department;

Back: corresponding to two traditional Chinese characters: (back) face, emperor (back);

Department: corresponding to three traditional Chinese characters: Wu (department), Guan (department) and Lian (department);

Calendar: corresponding to two traditional Chinese characters: (calendar) history, day (calendar);

Chinese: corresponding to two traditional Chinese characters: time (Chinese) and meaning (Chinese);

And so on, there are many such words (due to system problems, some traditional Chinese characters in this passage have been simplified, so just look them up in the dictionary)
