To date I have not found any network of people interested in landscape paintings in chinese ink. Perhaps that means it is high time to create such a network!

Several Chinese museums present part of their collections on line, for example:

The Shanghai Museum: http://www.shanghaimuseum.net/en/

The China Art Museum in Shanghai: www.artmuseumonline.or

The Suzhou Art Museum: http://www.szmuseum.com/En/Collection

A comprehesive collection is found at http://www.chinaonlinemuseum.com/. The displays and essays there build much on the collections at the National Palace Museum in Taipei: https://www.npm.gov.tw/en/. Other museums that present part of their collections on line are:

The Ashmolean Museum in Oxford: https://www.ashmolean.org/

The Cleveland Museum of Art: http://www.clevelandart.org/art/collection

The Metropolitan Museum of Art, in New York: https://metmuseum.org/art/collection

The Boston Museum of Art: http://www.mfa.org/node/9638

The Nelson-Atkins Museum of Art: https://nelson-atkins.org/
