Xi 'an's forest of steles is the largest treasure house of calligraphy art in China.
Abbreviation: Xi 'anbeilin is a treasure house.
1. Because "Xi 'an Forest of Steles" is a proper noun, it cannot be simplified as "Forest of Steles". For example, the Badaling Great Wall cannot be simplified as the Great Wall.
"Beijing Hotel" cannot be reduced to "hotel", "giant panda" cannot be reduced to "panda" and so on, and proper nouns cannot be reduced.
2. The "calligraphy art" in the "treasure house of calligraphy art" is the modification and explanation of the "treasure house". If we use "addition", we can see that it is a treasure house of calligraphy art, so calligraphy art will shrink.
I hope I can help you. Thank you.
