The Longyou Caves were only discovered late in the 20th century. At least 24 caves have been discovered so far. All of which were carved by hand. Although the overall excavation involved almost a million cubic metres of stone, there is no historical record of them or evidence of the work. Their origin is a complete mystery. At present there is no explanation for their existence. They represent one of the largest underground excavations of ancient times.
''Mongol noble women. Early 20th century.'' As incapacitated as Elizabeth I in her farthingaled splendour, these elite women signal their high status by wearing extended sleeves.By obscuring their hands the ladies show that they don't need to use them. Excessive overdressing in this fashion is a strange business. Rather than enjoying the ease wealth should bring them the wearers must suffer any number of exhausting inconveniences.
