In the history of Sung-Tsu (宋詞), both of Yeong Liu and Pang-Yen Chou had contributed prominently to the development of Man-Tsu (慢詞) and were all derived from the same origin of lineage. Although their Man-Tsus are similar to each other, the style of writing, the performance of artistry, the distinctive features and the linguistic talent are not identical. Previous works paid much attention to their works of Tsu, however, the inheritance, the enhancement and the differences and similarities between their Man-Tsu remain undiscovered. This article intends to compare and contrast their Man-Tsu to realize the development of Sung Tsu and to reveal the artistic style and trend of Pang-Yen Chou.
