Tang Taizong was also a poet, writer and calligrapher. His poems were compiled into Quantang Wen and Quantang Poems, with seven volumes, five poems and sixty-nine poems. Representative works include Preface to Emperor Fan and Golden Mirror. Emperor Taizong liked the calligraphy of Wang Xizhi, a famous calligrapher in Jin Dynasty, and was best at flying white calligraphy. Tang Taizong also attached great importance to the study of calligraphy, and his works such as brushwork, fingering and brushwork also played a guiding role in calligraphy. Emperor Taizong's admiration for Wang Xizhi's calligraphy led to a calligraphy innovation movement during the Zhenguan period, which unified the situation that Wang Tie, the southern teacher, and Wei Bei, the northern teacher, were independent since the Northern and Southern Dynasties, and made Wang Shu an authentic calligraphy style in the country.
