What mood did Xu Wei's Ink Grape express in Ming Dynasty?

In the Ming Dynasty, Xu Wei's Ink Grape is intended to express his infinite feelings of unappreciation and fearlessness, to express his old, weak and lonely feelings, and to express his helplessness and grievances that "heroes are useless". I was "idle" when I should have made great achievements, and my regret and resentment were expressed by the word "idle".

Xu Wei's painting achievements are mainly reflected in the freehand brushwork of flowers and birds, and Ink Grape Map is a work that can represent Xu Wei's freehand brushwork style. This painting has a strange composition, depicting a bunch of grapes with branches and leaves extending from the right. Because the branches extend out of the picture, there is still a blank in the middle, which looks very casual. The vines are scattered and drooping, and the branches and leaves are scattered. With bold and vigorous ink painting techniques, the momentum of people and the crystal clear effect of grapes are created.

The mnemonic framework is as follows:

1. Background: Flower-and-bird painting reached the artistic peak of freehand brushwork in ink and wash in the late Ming Dynasty, and Xu Wei was the representative of freehand brushwork. His works include "Ink Grape Map", which is now in the Palace Museum in Beijing.

2. Content of the work: In the picture, the old vines are scattered and drooping, and a bunch of grapes are upside down, crystal clear. Ink painting describes grapes, stippling branches and leaves, writing with a pen, getting the shape rather than seeking the shape, and writing poems in the painting, which sets off the author's infinite sense of depression.

3. Artistic features: This work is a freehand flower-and-bird painting in paper and ink. The composition is strange, and the grape branches with ink strokes extend obliquely from the upper right. Using cursive brushwork to express branches and vines, painting leaves with splash ink, and ordering grapes with ink full of moisture seem to be random, but it creates an imposing manner. In terms of techniques, rough and bold is its emotional appeal, and poetry and calligraphy are freely and fully combined in the picture.

4. Overall evaluation: The author combines the ink grape with his own life experience, a kind of helpless resentment and struggle that he has suffered a lot and is hard to pay, and expresses it with pen and ink, which raises the expressive power of ink to a new height.
