I experienced the Naadam Festival in China's Inner Mongolia in this year. Naadam meant "games" in Mongolian. It's represented by three events: horse racing, wrestling or archery, which are all so exciting to watch. Before the game, the competitors sang and danced happily, waved their arms. After these amazing performance, the wrestling competition began.
I absolute enjoyed the horse races. However, I was surprised that the riders was children of the same age with me. In beginning, I was worried about their safety, but the locals said they enjoyed them by riding horses all the life. At that moment I started to understand what people say "Horses are at the heart of Mongolian culture."
