A modern calligrapher whose pen name is Pioneer?

I wonder if you are talking about Zhang Xianfeng.

Pen name Quan Zhengzhai master, northern hermit. China is one of the six masters of calligraphy and painting. His calligraphy works can be traced back to the pottery bricks and bones of Yin, Shang, Zhou and Qin Dynasties, and also serve as bamboo slips of Han, Wei and Jin Dynasties, closely following the charm of Tang, Song, Ming and Qing Dynasties, which is the only way for Qin and Li Dynasties. ?

The main artistic achievement of his calligraphy: Long Song's China epic "Thousand Characters" 1052 words?

Master Shen Peng commented on Zhang Xianfeng's calligraphy method in Qin Dynasty, China: The pioneers' calligraphy is flowing, complicated but not redundant, free and changeable, and it seems to have traces of famous artists, but it is an open-minded, cheerful, fluent and natural unique style-Shen Peng.

Ouyang Zhongshi also has such an evaluation: the brush strokes of the pioneer teacher, Cao Mengde's boldness, Su Dongpo's boldness of vision, Song Huizong's delicacy and Wang Xizhi's agility can all be seen in the ink. Character and conduct, great talent and great ingenuity, romantic songs, are always reflected in calligraphy. -Ouyang Zhongshi.

I hope this answer will help you!
