The Yuan dynasty created this thing called a whistle arrow. The whistle arrow was used in battle to scare away opponents by making a terrifying noise in the air. They also created gers. Gers were Mongolian tent homes that were 9 feet tall and had a 15 feet perimeter, also there was a hole on the top to let smoke come out. Gers were useful because they were portable also, so it was convenient.
