Did the master write "Xi 'an" at Xi Railway Station?

These two words were written by Wu Sanda, a calligrapher familiar to the citizens of the ancient city. His calligraphy has an indescribable verve, cadence and heroism. He wrote the inscription "Dedicated to Dr. Sun Yat-sen" for the Mausoleum of the Yellow Emperor, "China Northwest Airlines" for the Xi Airport and the station name for the Xi Railway Station.
