During the reign of Emperor Taizong (Li Shimin), he served as the Vice Director of the Secretariat (Neishi Shilang), a key member of the court's core decision-making layer.

Core Knowledge Points

1. Meaning of Official Titles:
* Secretariat (Neishi Sheng): In the early Tang Dynasty, to avoid the taboo of Emperor Taizong Li Shimin's name (the character "Min"), the "Zhongshu Sheng" (Secretariat) was renamed "Neishi Sheng" (Secretariat).
* Vice Director of the Secretariat (Neishi Shilang): Equivalent to the original Zhongshu Shilang. Responsible for assisting the Director of the Secretariat in drafting imperial edicts and participating in confidential decision-making. This position was prestigious, equivalent to the level of a Vice Prime Minister.

* Diplomatic Mediation: Tang Jian was skilled in rhetoric. He served as a special envoy to regimes such as Xue Rengao and the Turks. Multiple times, he resolved conflicts during crises, demonstrating superb diplomatic wisdom.
* Straightforward Remonstrance: During Emperor Taizong's reign, he frequently offered suggestions on governing strategies and policies toward surrendered generals, reflecting the political atmosphere of "shared governance between ruler and ministers" in the early Tang.

Connection with the Zizhi Tongjian

In the Zizhi Tongjian, edited by Sima Guang, Tang Jian's image spans from the early Tang to the Zhenguan era:

* Diplomatic Records: The book details Tang Jian's mission to Xue Rengao. At the time, Li Yuan sent Tang Jian to persuade surrender. Relying on his personal courage and eloquence, Tang Jian maneuvered within the enemy camp. Although he did not succeed immediately, he provided key intelligence for the subsequent military operations of Li Yuan and his son Li Shimin.
Political Remonstrance: In Zizhi Tongjian* Volume 193 and other sections, it is recorded that during his tenure as Vice Director of the Secretariat, Tang Jian offered differing opinions on some policies of the Taizong court (such as the treatment of minority leaders and official appointments). By recording these dialogues, Sima Guang aimed to showcase Emperor Taizong's virtue of "accepting advice" and Tang Jian's loyalty and integrity.
* Institutional Background: The records regarding the "Secretariat" (Neishi Sheng) in the book indirectly reflect the historical background of official system reforms in the early Tang, helping readers understand the impact of the taboo system on the administrative structure.

Historical Insights

Tang Jian's deeds in the Zizhi Tongjian are not just fragments of a personal biography, but a microcosm of early Tang political wisdom.
