In Aguda's days, palaces were not much more than tents, but in 1123, the Jurchens built their first ancestral temples and tombs (where the captured Song emperors Huizong and Qinzong were to venerate the Jin emperors' ancestors in 1128), and in 1124 the Jin dynasty's Emperor Taizong ordered a Han Chinese architect, Lu Yanlun, build a new city on uniform plan. The city plan on Shangjing emulated major Chinese cities, in particular Bianjing, although the Jin capital was much smaller than its Northern Song prototype.
