Introduction to Duxianfang: Duxianfang was established for Hu Zongming, the deputy imperial envoy of the capital. In the Han Dynasty, Zhongcheng was appointed as the chief of the Yushitai, which was called Duxian. In the Ming Dynasty, the Yushitai was changed to the Duchayuan, and the Duxianfang was equivalent. In the previous dynasty, Zhongcheng was the censor, so the place was named "Du Xian".
