Wan Li's calligraphy

You can't.

This calligraphy in the title describes the situation of frontier fortress, which is more tragic. The Long March people did not point out the cruelty of war, but expressed the poet's deep affection, which was not suitable for hanging at home.

Not all calligraphy can be hung at home, but positive calligraphy should be hung at home, which will give people a positive psychological hint.
