Introduction to Jinghai Temple: Jinghai Temple, located on the west side of Lion Rock, was built during the Yongle period of the Ming Dynasty. It was built by Zhu Di, the founder of the Ming Dynasty, to commemorate the triumphal return of the navigator Zheng He from his voyages to the West. Jinghai Temple is the place where the first unequal Sino-British Treaty of Nanjing was signed in June 1842 in modern history of my country. It is now the exhibition hall of historical materials of the Treaty of Nanjing.
