What is the most cost-effective way to go from Hechuan, Chongqing to Chashan Bamboo Sea, Yongchuan? (including car, meals and accommodation)

Hello, my friend, you want to take the through train from Hechuan to Yongchuan. You can also take the train from Hechuan to Luzhou and pass by Yongchuan. Yesterday, my friends and I also said that we would go to Chashan Zhuhai to play. At first they said we didn't want tickets. We drove for a long time to the door, and there was an iron pole blocking it. I'm going to take it away As a result, two people said they would buy a ticket for 30 yuan. When you see other cars coming in, don't. I suggest you go by bus. I wonder if you want a ticket. Then you can see the situation. To tell the truth, the air on the mountain was good all the way by car. Open the window, the wind is blowing, which is very comfortable.
