The artist has been learning mnemonics since 2014. He stores a large number of dream diaries in a memory loci. Each memory loci is composed of three elements: space, number, and metaphor. Through the method of mnemonics, the artist can quickly search for dreams from the past. Memory Loci_ Blind Horse shows a metaphor about dreams, a knight without legs and a horse without eyes. When the knights is awake, the horse is controlled by the knight, and when the knight is asleep, the knight disappears, and the blind horse running around without purpose.
