This is "The Corridor" which links the Hall of Liu Bei and Liu Bei's Mausoleum in Wuhou Si (or Temple of the Duke of Wu) in Chengdu. I have seen this scene captured by several photographers including in PBase, and indeed it is most photogenic. The S-shaped corridor, lined on both sides by classical red Chinese walls with overhanging green and shady bamboo plants, evokes a certain kind of charm and atmosphere which strike all visitors as they enter through the moon gate from the Hall of Liu Bei into The Corridor.
