Was Su Dongpo's Biography translated by Song Biyun or Zhang Zhenyu? thank you

The answer is somewhat misleading. Zhang Zhenyu and Song Biyun are both English versions of Mr. Lin Yutang, and both versions have their own merits. In addition, Mr. Lin's original work has strong artistic elements, so translation cannot be separated; Professor Li wrote another biography of Su Dongpo from the perspective of textual research, so we can't simply compare the three.
