Students from Shahe No 3 Primary School in Baotou, North China’s Inner Mongolia autonomous region, display paper-cuttings they have made, April 4. Paper-cutting is one of the most important folk arts in China, with a history that can be traced back to the Western Han Dynasty (206 BC-AD 24) when Cai Lun invented paper. Baotou paper-cutting incorporates grassland and nomadic culture into art, and was listed as part of China’s cultural heritage in 2010. [Photo/Baotou Daily]
