The Xijin Studio, a magnificent two-story hall, was constructed by Heshen, a powerful official during the Qianlong reign (1736-1795). Inspired by Leshou Hall (Hall of Joyful Longevity) in the Forbidden City, Heshen lavishly decorated the Xijin Studio with precious nanmu wood, exceeding the standards allowed for a subject. This excessive luxury was one of the reasons for Heshen's downfall.
Prince Kung's Palace was once home to The Consoling Letter, a treasured calligraphy masterpiece by Lu Ji from the Western Jin Dynasty (265-316) that was carefully preserved in the studio. The studio's name is a tribute to this valuable possession.
To house Prince Kung's vast collection of antiques, the east and west side halls of the Xijin Studio were designated as "Legu Studio" and "Er'er Studio", respectively. These names humbly acknowledged the insignificance of these collections in comparison to the treasured The Consoling Letter.
