Why is the feng shui in Xi Qujiang not good?

Xi 'an Qujiang Royal Garden has an irreplaceable position in the history of gardens in China, which initiated the ancient garden art in China. As early as the pre-Qin period, it has been planned as a royal garden by the imperial clan of Qin State, and the famous Daqin Palace Yichun Garden is located here. Qujiang itself has beautiful scenery, and the water system here is natural, so there is no need to build a recycling system. Therefore, the Sui Dynasty renovated this place into a fairyland with beautiful scenery without spending too much manpower and material resources. Qujiang has a poor reputation for many historical reasons.
