The main material of the Aggregation series, which has been going on since the 1990s, is triangular Styrofoam of various sizes wrapped in copies of old books. The artist describes it as a cloth that contains the soul and spirit of the nation. A relief-like screen completed by tying up tens of thousands to as few as thousands of 'gobon modules' in strings is a melting pot of the wisdom and stories of our ancestors accumulated over a long period of time. Stories from different times and spaces combine in a new context to create other stories, causing harmony and conflict.
