Urgently seek the bus route from Yongchuan to Jiangjin Baisha

I've been on this line, 1. If you don't take the expressway, go from Yongchuan to Linjiang first. There is a secondary road in Linjiang that passes through Wushi Town and Youxi. You cross Jiangjin Yangtze River Bridge along the secondary road. Turn right at Nanqiaotou to Simian Mountain, and then turn right through Ciyun Town in Lishi. The next town is Baisha. 2。 If you want to take the expressway comfortably, Yongchuan-Zouma-Jiangjin (Chengdu-Chongqing Ring Expressway) -G93 (Chongqing-Luzhou Expressway or Chengdu-Chongqing Ring Expressway)-Baisha. I took 1 when I went, and I took 2 when I came back. However, expressway is still a little incomplete.
