François Chastanet, the author of
‘Dishu: Ground Calligraphy in China’ survey, explained Outriders he spent two months in China in 2011 travelling from Beijing to Xi'an, Shanghai, Shenyang and other cities interviewing several calligraphers about Dishu. He used written questionnaires (about eight questions) and “there was a consensus on Dishu started in 1991 or 1992, in a park in the north of Beijing”, he admitted.
