Second, the faster route: Leshan to Meishan, then take the shuttle bus from Meishan to Renshou and get off at Heilongtan. This road can also be driven by car.
The first route has to go through Jingyan. The road from Jingyan to Renshou is a bad word, and the other roads are ok.
The second route takes the expressway, but the road from Meishan to Heilongtan is not easy either. During this period, you can also build a road in a one-way street, which is only about ten kilometers, but it is better than the road from Jingyan.
