李煦幼子李以鼐小考

A Brief Study on Li Xu’s Youngest Son Li Yi-Nai

皮述民教授曾主張《紅樓夢》中的寫作素材除一部分取自江寧織造曹寅家外，也不乏源出蘇州織造李煦家者，進而揭舉李煦長子李以鼎就是在小說創作過程中扮演重要角色的脂硯齋。由於證據不足，其說沒能獲得共識，但亦有學者受到啟發，並提出李以鼎之弟李以鼐才是脂硯齋的主張，希望借此鬆解開「脂硯何人」的紅學死結。但因大家對李以鼐生年的判斷相差近二十年，對該假說可否繼續開展造成了基礎障礙。有鑒於此，本文在重新深入探析李煦幕友沈槱元、成達可、李果等人所寫的相關詩文以及現存共六次纂修的《昌邑姜氏族譜》後，得出李以鼐為李煦於康熙五十五年九月十五日所生之行三次子的結論。

Professor Pi Shu-Min once claimed that the materials for writing The Dream of Red Chamber were not only obtained from Jiangning’s Official of Royal Clothes Cao Yin’s family but also originated from Suzhou’s Official of Royal Clothes Li Xu’s family. He further revealed that Li Xu’s eldest son Li Yi-Ding was the real identity of Zhi-Yan Zhai, a person that played an important role in the creation process of the novel. While insufficient evidence prevented this proposition from acquiring general agreement, some scholars were inspired by it and suggested, in the hope of solving the deadlock of “who Zhi-Yan was” in Red studies, that the real identity of Zhi-Yan Zhai was Li Yi-Ding’s youngest brother Li Yi-Nai. Nonetheless, scholars’ judgments on Li Yi-Nai’s birth year differed by nearly two decades, posing a basic obstacle to whether this hypothesis can continue to develop. In view of this, this article once again scrutinizes and analyzes the relevant poems and articles written by Li Xu’s subordinates Shen You-Yuan, Cheng Da-Ke, Li Guo, etc. and the existing Genealogy of the Jiang Family in Changyi, which has been edited and collated six times. The conclusion is that Li Yi-Nai was Li Xu’s third son, who ended up ranking second (because his second elder brother died early), and was born on September 15th in the 55th year of Kang-Xi era.
