ZHENGZHOU, CHINA—Xinhua reports that the rammed-earth base of a fortified gate has been found in the ancient capital of Luoyang, at the site of an imperial palace dating to the Northern Wei Dynasty (A.D. 386–534). Liu Tao of the Chinese Academy of Social Sciences said historical records indicate that officials of the Northern Wei Dynasty would park their sedan chairs and carriages outside this gate before entering the palace’s main hall to see the emperor.
