What are the outstanding representative works of Yang Weizhen's calligraphy?

Yang Weizhen's works handed down from generation to generation include Preface to Yuefu, Poems of the South of the City by Zhang, Poems of Waves by Zhang, Poems of Hexian, Plum Blossom and Yujing.

As a generation of celebrities, Tieya's poems are known as "Tieya Nanyin Harmony Song". In his early years, calligraphy imitated the Tang Dynasty, and absorbed the essence of Daoyin master tablet. Its origin can be found in the regular script Epitaph of Zhou Shangqing and the running script Zi Ming. After middle age, the style of calligraphy has changed, such as "Poems of Harmony in the South of the City", "Tang Cheng Qu" and "Zhen Jing Temple Collection", all of which are a mixture of letters, lines and grass, and the brushwork is ups and downs, natural and naive, without too many rules. This book is written in the style of ancient Li Zhangshu, giving people a feeling of being graceful. As the Qing people said: "To the extreme, there is a kind of unconstrained style", unconstrained, with messy strokes and "troubled times".
