The Blue Calico represents the collective wisdom of the Chinese nation, and its eight-hundred-year old history shows the creativity of the nation and the sustainability of traditional culture. The Blue Calico emits a cultural ambience which is simple, unsophisticated, pure, and fresh with a meaningful theme, exquisite craft, and implied style. The original and seemingly natural craft has an influence on the world, and the blue calico, in itself, has historical values, playing an irreplaceable role today. 'Nantong Indigo Blue Cloth Dyeing and Finishing Skills' has been included in the first collection national intangible cultural heritages. In addition, Nantong is the 'Home of Blue Calico'.
