Long Corridor (Chang Lang):The Long Corridor was originally built in the 15th year of Emperor Qianlong’s reign (1750) and then rebuilt in the 12th year of Emperor Guangxu’s reign (1886) because the Anglo-French Allied Forces burned it down in 1860. It starts from Inviting the Moon Gate in the east and ends at Shizhang Pavilion in the west, covering a distance of 728 meters with its 273 sections. Of all the corridors in Chinese classical gardens, the Long Corridor is the longest. On the beams are more than 8,000 colorful paintings depicting stories from Chinese classical novels, folk tales, landscapes as well as flora and fauna. Four pavilions, “Mesmerizing Scenery”, “Harmonizing with the Lake”, “Autumn Water” and “Clear and Carefree”, with octahedral structures and double eaves, were built intermittently along the corridor. Taking the Hall that Dispels the Clouds as the center, the Long Corridor stretches symmetrically to the east and the west along the foot of the hill and the water bank, linking all the structures scattered along the Longevity Hill side into a whole.

Hall for Listening to Orioles (Tingli Guan):Initially built by Emperor Qianlong for his mother to watch operas, this theater with its two-storey stage was named the “Hall for Listening to Orioles” because in old times, people often compared beautiful voices to the singing of orioles. It was burned down by the Anglo-French Allied Forces in 1860 and was rebuilt during the reign of Emperor Guangxu. Before the completion of the Great Stage in the Garden of Virtue and Harmony, the Empress Dowager often watched operas and held banquets here. Now, the hall serves as a restaurant specializing in imperial court cuisine and has become famous for having received over a hundred foreign leaders.
