+            The path of sound flows like the Milky Way through which the stars circulate, always there, whether you are listening to it or not.
           </p>

+          The permanence of this eternal parade gives us final consolation. Sometimes we think that we are space debris in infinite orbit, but The moment it is observed, it is no longer loneliness or forgotten, but remembered.
+		  </p>
           <p>
-            «Walking Toward the Flow» consists of a total of five 'flock' of sounds: the sounds of promises, the sounds of speaking, the sounds of the body, the sounds of objects around, and the sounds of someone. They will flow in groups for about 3 minutes each and a total of 15 minutes or more.
-          </p>
-          <p>
-            On the night of January 27 (Thursday), the «Walking to the Flow» parade will be broadcasted along with a live performance at the 'the Night of Ideas' hosted by Cultural Service of the Embassy of France in Korea, Liszt Institut Hungarian Cultural Center Seoul and Embassy of Belgium in Seoul and sponsored by UNESCO Korea and Institut Français. Thank you for your participation and interest.
+            «Walking towards the Flow» will perform offline on November 27 (Sun). In the performance, the sounds gathered on the website can be heard in the physical space, and audiences can walk and stop together to hear the voices of those who empathize with the flow.
           </p>

+We look forward to your interest and participation in the online recruitment and offline performances.
