The Underground Palace consists of three aligned vaults: the Ante-Chamber, the Sacrificial Chamber and the Burial Chamber. Each chamber is provided with an entrance gate as massive as the main gate.  

    The Ante-Chamber is now bare. The Sacrificial Chamber, flanked with an annex chamber on each side, contains three white thrones. The central one, carved with dragons in high relief on its back and sides, was for the emperor, who was flanked in death by two empresses on thrones carved with phoenixes. In front of each throne is a set of five-altar pieces and a large blue-and -white porcelain jar still containing oil and wick in a bronze tube. This is called "everlasting lamp"(3) which was supposed to provide "everlasting light". Midway along the side walls are simple arched doorways leading into the annexes. Each annex contains a stone couch on which an empress's coffin was to rest. In the center of each couch there is a square hole in which yellow earth was placed, presenting a secret connection between the coffin and the earth. At the end of each annex is a huge gate with a self-acting stone. Beyond the gate is a vaulted passage which is blocked. The passage was intended for the entombment of the empresses should they die after the emperor, as no one was supposed to disturb his corpse. From www.liuxuepaper.com.

    In the Burial Chamber, the largest part of the tomb, stand three red-lacquered coffins, side by side on a white marble platform. The one in the middle is the Emperor's coffin, with the First Empress's on the left and the Second Empress's on the right. Inside each coffin there is another coffin, and thus, each imperial corpse is held in two coffins, one kept within the other. In the narrow spaces between the three sets of coffins are two pairs of vases and three boxes which originally contained a wooden imperial seal and wooden tablets recording the bestowal on the emperor of his posthumous title. There is also an iron helmet decorated with gold and jewels, a suit of mail, a sword, a bow, and iron-tipped arrows.

    ON either side of the coffins are 26 wooden chests that contain wooden figurines, women's head-dresses decorated with golden phoenixes and jewels, wooden seals with the posthumous titles of the empresses, jade belts, strings of jade pendants, robes, shoes and sets of gold chopsticks, spoons, cups, and wash-basins. Also on the platform were wooden models of sedan chairs, coaches, spears, bows, arrows, flagstaffs with silk banners and other objects used in imperial processions.

    When the emperor's coffin was opened, a silk shroud, jade cups and jade bowls with a gold cover were first exposed. The shroud was then carefully rolled back, revealing among other precious objects a royal crown which is the only royal crown excavated so far in China. Of Emperor Wan Li, only bones and hair remained. He wore a beard, and his long hair in a top knot was secured with long gold pins. The "dragon robe", in which he was buried is not so well preserved as a similar one buried with him. Rolls of silk, all in gorgeous patterns and many woven with gold thread, form his mattress and bedding. Both empresses' coffins contained phoenix coronets and other headdresses, bronze mirrors and gold boxes for cosmetics and toilet articles. The coronets are of fine gold mesh with dragons and phoenixes, each adorned with more than a hundred germs and five thousand pearls. ()
