The Yimen Gate, with a three-bay facade, features a central door panel flanked by red wooden fences that subtly divide the space, ensuring unobstructed visibility. On either side of the main gate, smaller auxiliary doors are strategically placed. The Yimen itself is designed as a hard-gable-style entryway, measuring 5.6 meters in depth—smaller in both form and scale compared to the grand main gate. This second gateway at the Zhili Governor’s Mansion, known as the Yimen, embodies the phrase "having rituals that can be emulated." During the Qing Dynasty, official court etiquette was incredibly elaborate and complex. Although the Governor of Zhili held the prestigious rank of Second Grade, he often received an additional appointment as Minister, elevating his status to First Grade. As a result, very few of his peers were honored with the privilege of personally greeting him outside the Yimen; most visiting officials were instead directed to enter through the gate’s side entrance instead.
