What's the difference between calligraphy and European style?

The inkstone body was created by Yan Zhenqing, a calligrapher in the Tang Dynasty. Together with Liu Gongquan, it is called "Yan Liu" and "inkstone Liu Jingu". "Yan Ti" is aimed at Yan Zhenqing's regular script. Its regular script structure is square and dense, the strokes are horizontal and light, the brushwork is vigorous and round, and the momentum is solemn and vigorous. The strokes form the swallowtail of the silkworm head, while the straight drawing forms the shape of a crossbow. The contrast between strokes is complicated. Pinch the end of the hook, kick out the sharp edge and show off its spirit. His brushwork shows a tortuous rhythm. Its straight hook, flat hook and inclined hook are full of potential, with uniform curvature and strong roundness. Its folding pen is secretly rotated by holding the pen, forming an inclined plane to fold down, and it is drawn by "folding pin". Structurally, it is dignified and steady, with a wide middle palace and dense shapes around it. It does not occupy the lateral advantage of the center of gravity, nor does it occupy the left and right advantages, but shows people with a symmetrical positive image like turning inside. On the white cloth, there are rows of words and dense lines, and the momentum is taken by shape, not by thinning. Ou Yangxun is known as the first regular script in Tang Dynasty for his rigorous brushwork and precipitous brushwork. His calligraphy achievements are based on regular script, with bold brushwork and unique structure, which is called "European style" by later generations. Originally from Han Li, he was vigorous and rigorous in statutes. He sees risks in plain sight, with elegant composition, interspersed strokes and proper arrangement. Its "eight tricks" are: (point) like falling rocks from the summit; (Yoko) is like the new moon in the sky; (Horizontal) Like Wan Liyun; (Vertical) Long live the withered vine; (vertical ge) If Jinsong is folded upside down, it will fall off the cliff; (folded) like a crossbow of hosts; (left) If a sword breaks a rhinoceros horn; A wave of strokes is often repeated three times. Give you some comparisons between the two:
