The city of Shenglong Emperor is located in Hanoi, Vietnam, where many Vietnamese dynasties were built. It contains a unique and invaluable cultural heritage and has significant global value. It was listed as a World Heritage Site in 2010. The Shenglong Emperor City is a three-dimensional picture of Vietnam's feudal dynasty, precipitating layers of historical traces, recording the dynasty's glorious past, still with poetic calm and quiet, but now it is a broken wall.
