How do I drive from Chengdu to Zigong on the Chengzi-Luxin Expressway? Where can I get on the expressway in Chengdu? Where can I get off the expressway in Zigong?

I have three pictures here. The first one is the starting point of Chengdu on the Chengdu-Zilu Expressway, at the South Third Ring Road. The second one is the Zigong Dashanpu exit after turning from the Chengdu-Zilu Expressway to Neiyi Expressway. The third one is Zhang is the Zigong Nanhu exit. Both exits can lead to Zigong urban area.
