This special livery was unveiled 300 days before the opening of the 46th Shanghai Skills Competition, for which China Southern acts as the official carrier. The core pattern of the scheme is the Mortise and tenon which usually connect two pieces of wood or of materials and symbolize the spirit of craftsmen. The "Nengneng" and "Qiaoqiao" mascots representing craftsmen are visible on the two sides of the aircraft (their position being reversed). Also visible are the urban landmarks of the Tianjin-Hebei region and the Guangdong-Hong Kong-Macao Greater Bay Area.
