1. Briefly describe Wang Xizhi's artistic contribution. 2. Briefly describe Gu Kaizhi's artistic contribution and write as few words as possible.

Wang Xizhi's artistic contribution: increased the destruction of ancient law and changed the simple calligraphy style of Han and Wei dynasties into fine and beautiful calligraphy style. In a word, the introduction of Chinese character writing from practicality to the realm of paying attention to techniques and tastes is the awakening of calligraphy art, which indicates that calligraphers not only discover the beauty of calligraphy, but also can show it. Few later calligraphers have not copied Wang Xizhi's calligraphy posts, so they have the reputation of "book saints".

Gu Kaizhi's outstanding achievement is that his figure paintings are vivid and vivid with daily life as the theme. The brushwork is like silkworms spinning silk, with both form and spirit. His paintings inherited and developed the fine tradition of ancient realism, broke the previous atmosphere of paying attention to religious themes, and became the most precious heritage in the art treasure house of the great motherland. Most of his masterpieces have been lost, and now there are manuscripts of scrolls such as "The Goddess of Luo" and "The True Picture of Nvshi", which are regarded as treasures by generations.
