本文主要針對余嘉錫先生《世說新語箋疏》一書中，引用的程炎震說法之商榷與討論。亦即在其書〈政事第三〉十八條中記載了王濛、劉惔與支遁相訪何驃騎何充一事，程氏認為此說有誤，當為竺法潛深公而非支遁林公。此說為包括余書以及其他《世說新語》等校箋之書籍所接受。筆者在此運用文獻資料，兼顧情理與事理之相互對照，指出其說首先忽略了何充與竺法潛之情誼與輩分之關係，而且何充與支遁兩人有明顯交遊之證據，其次支與王劉之關係遠比竺法潛與王劉關係來得深厚，故從以上諸證來看，程氏之說有誤 ，進而主張維持原有的支遁林公之說。

The aim of this paper is to discuss a specific quotation from Cheng Yan-zeng(程炎震)in Yu Jia-xi's (余嘉錫) Note and Commentary on Shi Stuo Xin Yu 《世說新語箋疏》。In the third chapater of the "Government Affair", it mentions the visits of Wang Mong (王濛), Liu Yan (劉惔) and Zhi Dun (支遁), to General He Chong (何驃騎何充). Cheng proposed that one of the visitor might be Zhu Fa-qian (竺法潛) Master Shen (深公), instead of Zhi Dun (支遁) Master Lin (林公), Yu and other authors of Shi Shuo Xin Yu accepted Cheng's proposal. Base on historical texts we found that Cheng has ignored the status and the relationship between He Chong and Zhu Fa-qian. He did know Zhi Dun. There are closer relationship between Zhi and Wang or Liu than Zhu Fa-qian. We conclude that Cheng's point of view might not be correct, and suggest the original point be maintained.
