Thank you for the predecessors who mined the mine, but from the perspective of play, this attraction is a huge pit. Fortunately, this year's ticket is free. It is said that the previous ticket has to be 80 or even 100. How can I get it? The No. 3 mine pit is at the entrance of the scenic spot, and it takes only 3 minutes to walk. There is only this place to see. Although the ticket is free, you need to take a shuttle bus to go to a mine above. It takes no more than 8 minutes to get to and from. It costs 40 yuan. The shuttle bus of dozens of kilometers in the Erzis Grand Canyon is also 36 yuan. I don't know how dare you charge this fare so expensive? If you have no obsession with entering the mine, there is no need to buy a shuttle bus. It is enough to see the No. 3 mine at the entrance of the scenic spot! If you resume receiving tickets in the future, there is no need to come in. It is enough to see the museum next to the Grand Canyon and the photos of the No. 3 mine on the Internet!
