Guo Xiaotu, nicknamed Guo Feng, is from Heze, Shandong. Professional painter, good at cursive script, now living in Beijing. I like calligraphy since I was a child, and I am especially good at drawing bamboo. Zhang Xu and Huai Su are better than others in their hard work, brushwork and poetry, and they have won the essence of their brushwork. His calligraphy works are freely opened and closed, freely retracted, while flying like a phoenix, magnificent, vigorous and unrestrained, and rich in heritage.
