Wu Changshuo was a famous calligrapher and painter in the late Qing Dynasty. I haven't painted a bustling picture of Gusu, but I have an inscription "A bustling picture of Gusu", which is quite different from Liao Bo's "A bustling picture of Gusu". That is to say, his works are colored on paper, with a length of 1200cm and a width of nearly 37 cm, while Wu Ti is a paper-based painting with a core and a title of Wu Ti, with a total length of 655 cm and a width of 33 cm. Both the prosperous time picture of Gusu and Wu's prosperous time picture of Gusu record a boundary painting by Xu Yang, a court painter in Qing Dynasty, which is called "the prosperous time gestating picture". This picture with the theme of Wu is a combination of painting and calligraphy. Its painting core is colored with yellow silk, only 520 cm long and 29 cm wide. It is a painting made according to the format of Zhang Songze's "The Riverside Scene at Qingming Festival", that is, all works are colored with yellow silk, with the same size and specifications. This fact proves that the original work of the prosperous time breeding map inscribed by Xu Yang in Qing Dynasty no longer exists, but the title of the map named the prosperous time map of Gusu was renamed by later generations, and was recognized by the social authority and the social calligraphy and painting circles at that time, that is, all the maps named the prosperous time map of Gusu should be original works reloaded or copied by later generations. The original record is that this scroll is recorded in the shiqu Bao fen Xu, that is, it is an original if it is consistent with this Qing palace record, but not an imitation. The archives of Painting and Calligraphy of Qing Palace compiled by Shi Qubao are now in the National Library of China. As long as the records of this file are displayed online, netizens will judge calligraphy and painting themselves and become masters of painting. A large number of Wu's paintings in the market, as long as the title and core are printed on a piece of drawing paper or a modern chemical imitation silk, a large number of such soy sauce paintings are wholesale online. Its price is 20-30 yuan RMB wholesale price.
