Murong Xi
Murong Xi soon started a number of heavy construction projects. In 403, he built Longteng Chateau (龍騰苑) within his imperial garden, described as occupying over two square kilometers and requiring forced labor from 20,000 men. He further built an artificial hill within the chateau that was described as 500 steps wide and 57 meters high. Later that year, he honored his mother Consort Duan as empress dowager, and he created Consort Fu Xunying as empress.
