Who referred to the European style in calligraphy?

The "European style" in calligraphy refers to Ou Yangxun. Ou Yangxun was born in Linxiang, Tanzhou (now Changsha, Hunan). Dr. Taichang, the official of Sui Dynasty, was named Prince Geng Ling in Tang Dynasty, also known as "Ouyang Lvgeng". Because his son Ouyang Tong is also good at calligraphy, he is also called "Big Europe". Ou Yangxun's calligraphy enjoyed a high reputation in the Sui Dynasty. In the Tang Dynasty, Ou Yangxun was still teaching calligraphy in Hong Wen Pavilion. Ou Yangxun's eight-character style is unique, and his regular script method is rigorous and his brushwork is steep, which is unparalleled in the world. He is called the first regular script in Tang Dynasty. He and Yu Shinan were both famous for their calligraphy in the early Tang Dynasty, and they were called "Ou Yu".

According to historical records, a beginner of calligraphy once studied Wang Zi, but he lived a steep life. Legend has it that Ou Yangxun once spent a lot of money to buy a map of Gui Zhi for Wang Xizhi's godson to learn Chinese characters, copying it day and night and studying hard. On another occasion, when he went out with Yu Shinan and saw a stone tablet written by Suo Jing, a calligrapher of the Jin Dynasty, he sat on the floor. He carefully observed and described the tablet for three days, which shows that Ou Yangxun has a strong interest in calligraphy. Later, he extensively studied the inscriptions and stone carvings of the Northern Dynasties, absorbed the strengths of some local calligraphers, and then integrated them into the official script, forming a calligraphy style of "vigorous and strange, strict statutes". Later generations saw the danger in the middle of the book and learned it first. The name is "European style" (also called "multi-style"). His inscription on the ritual spring of Jiucheng Palace is the pinnacle of regular script in Europe. His main works include the Buddha Taming in Huadu Temple, the tablet of Yu Gong Wen Yan Bo, the tablet of Huangfushengchen and the tablet of dreams.

Ou Yangxun's calligraphy is based on the characteristics of regular script in Han Li and Jin Dynasties, and also draws lessons from the inscriptions in the Six Dynasties, so it is widely used by various schools. The main features of Ou Yangxun's calligraphy style are rigor, neatness, honest and frank and vigor. Although the glyph is a little longer, it is white, neat and rigorous, the middle palace is tight, the main pen is elongated, it looks bold and unrestrained, dense and well-organized, surrounded on all sides, exquisite and vivid, just right. The combination of stippling and painting, the structural arrangement, is that the middle of the plane is steep and powerful, and the fonts extend to the right, but the center of gravity is still very stable, without the feeling of inclination, which is interesting and dangerous.
