Who are the authors of Spring Tide and Bright Moon on the Sea?

Zhang (about 647-730), a native of Yangzhou (now Yangzhou, Jiangsu), was a poet in the early Tang Dynasty. It is famous for "Moonlit Night on the Spring River", and it is also called "Wuzhong Four Scholars" with He, Zhang Xu and Bao Rong. There are only two of his poems, which are included in the whole Tang poetry, among which "Moonlit Night on a Spring River" is a well-known masterpiece. It follows the old theme of Sui Chen Yuefu, expressing sincere and touching feelings of parting and philosophical understanding of life. The language is fresh and beautiful, and the rhythm is melodious, which washes away the thick powder of palace poems, giving people a clear, empty, beautiful and natural feeling. Known as "a solitary poem covers the whole Tang Dynasty".
