When you arrive in Jiayang, you must go down to a mine and dig a few shovels of coal. It is a great experience. Going down the mine, you can feel the sound and light of the gas explosion, ride the monkey car, learn about the history and development of mining, and see a lot of mining machinery. Except for the time spent queuing for the monkey car, the whole process was very happy. Although I was exhausted after climbing the slope of the Cong Mine, it was still very interesting. I also saw a giant salamander.
