Architecture of Mongolia
The Xiongnu confederation ruled present-day Mongolia from the third century BCE through the first century CE, living in portable, round tents on carts and round yurts. The Xiongnu aristocracy lived in small palaces, and their villages were protected by huge walls. S. I. Rudenko also mentions capital construction built of logs. Archaeological excavations indicate that the Xiongnu had towns; their chief city was Luut Hot (Dragon City).
Sheshui
Huanglong, one of the Eight Immortals was named Qi Tianlong, and married Ho Xiangu. They lived on a boat, and often helped others. One year, the rain came down in torrents, the mountains burst, the fertile fields flooded, and the animals were slaughtered. Qi Tianlong and his wife rescued many villagers from the calamities. But the two of them became very tired, and were swept away by the floodwaters. Their bodies were found in the county in the north, and the couple were buried on the banks of the She River. In honor of the couple who saved their lives, the villagers built the Xianyou Tai and Xian You cave in front of the couple's tomb, dedicated to their memory. This touched the Eight Immortals, and every winter solstice after the couple's death, the group gathered here and give a wine libation as a sacrifice.
