Plaster industry

Tai'an is the key producer of plaster, sulphurite and granite, with the most amount of plaster designer. Since there are implications of "as stable as Mount Tai" and "weightier than Mount Tai" in Tai'an granite, it has been employed in many well-known Chinese buildings like Great Hall of the People, Tian'anmen Square and Monument to the People's Heroes at Tian'anmen Square.
