4. the source says, "Chinese calligraphy shows an incontestable esthetic quality.
   
   For this reason, the Chinese -- the intellectuals in particular -- decorate their studies with one or two calligraphies excuted on a silk scroll to imbue their houses with a refined and distiniguised atmosphere.
   
   They also follow the custom of putting up the two panels of their entry doors, or on either side of them, two parallel sentences written on two long pieces of paper.
   
   These two phrases often express a wish for a good year, delare an aspiration of the master of the house, or simply show his desire to add a note of distinction to his house."
