onto the mounting, as it gives form to the art. The art is fixed onto a four-sided inlay, made from paper or silk, thus providing a border. The artwork in the middle of the scroll is called huaxin (畫心; literally "painted heart"). There is sometimes a section above the artwork called a shitang (詩塘; literally "poetic pool"), which is usually reserved for inscriptions onto the work of art, ranging from a short verse to poems and other inscriptions. These inscriptions are often done by people other than the artist. Although inscriptions can also be placed onto the material of the artwork itself. The upper part of the scroll is called tiantou (天頭; symbolizing "Heaven") and the lower part is called ditou (地頭; symbolizing "Earth"). At the top of the scroll is a thin wooden bar, called tiangan (天杆), on which a cord is attached for hanging the scroll. Two decorative strips, called jingyan (惊燕; literally "frighten swallows"), are sometimes attached to the top of the scroll. At the bottom of the scroll is a wooden cylindrical bar, called digan (地杆), attached to give the scroll the necessary weight to hang properly onto a wall, but it also serves to roll up a scroll for storage when the artwork is not in display. The two knobs at the far ends of the lower wooden bar are called zhoutou (軸頭) and help to ease the rolling of the scroll. These could be ornamented with a variety of materials, such as jade, ivory, or horn. Method and processes Traditional scroll mounters go through a lengthy process of backing the mounting silks with paper using paste before creating the borders for the scroll. Afterwards, the whole scroll is backed before the roller and fittings are attached. The whole process can take two weeks to nine months depending on how long the scroll is left on the wall to dry and stretch before finishing by polishing the back with Chinese wax and fitting the rod and roller at either end. This process is generally called 'wet mounting' due to the use of wet paste in the process. In the late 20th century a new method was created called 'dry mounting' which involves the use of heat activated silicone sheets in lieu of paste which reduced the amount of time from a few weeks to just a few hours. This new method is generally used for
