For reference only, I hope it will help your physical characteristics. The widest part of Peking man's skull is slightly higher than the left and right ear holes, and gradually narrows upward, showing a parabolic outline. This is different from the fact that the widest part of the modern skull moved to the middle of the skull, and it is also lower than that of Neanderthals. Beijingers have flat skulls and sloping foreheads. Although higher than apes, but lower than modern people, slightly lower than Neanderthals. The average brain capacity of Beijingers is 1043 cubic centimeters, which is between apes and modern people. Their skulls are about twice as thick as those of modern people. The brow bone is thick and protruding forward, and the left and right sides are connected. There is an obvious sagittal ridge in the middle of the head, and a well-developed occipital lobe pillow in the back of the skull. Beijingers have a short face, a long snout and no chin. The nasal bones and cheekbones are flat and wide, and the cheekbones face forward, indicating that their noses are wide and their faces are low and flat. There is an obvious mandibular round pillow in front of the medial face of mandible. Their teeth, whether crown or root, are weaker than apes, and the texture of crown is simple, but it is much thicker and more complicated than modern people. In addition, the lingual surfaces of canine teeth and upper central incisors have finger-like protrusions extending from the basal tubercle to the cutting edge; The lingual surfaces of upper central incisors and lateral incisors are obviously shovel-shaped. The primitive preservation of Peking man's head is similar to that of Javanese, so they all belong to the development stage of Homo erectus. Beijing people's front teeth are shovel-shaped, with a wide nose and a low face, and there is a mandibular pillow in the front of the mandible, which shows obvious characteristics of modern Mongolian.

The medullary cavity of Beijing people's lower limbs is smaller and the tube wall is thicker (femoral medullary cavity only accounts for one third of the minimum diameter of spine, while modern people account for half; The tibial medullary cavity is smaller), but the size, shape, proportion and muscle attachment point are similar to those of modern people, which proves that they are good at walking upright. In addition to the smaller medullary cavity and thicker wall, Beijing people's upper limb bones are closer to modern people than their lower limbs, which shows that their upper limbs have been able to carry out activities very similar to modern people. The height of Beijingers is about 1.56 ~ 1.57 meters, calculated from a relatively complete femur length found.
