Scenic places on the way from chengdu to jiuzhaigou by car

Yes, there are many interesting scenic spots on the way, such as Dujiangyan Irrigation Project and Chuanzhuzi.
Dujiangyan is the oldest and only surviving no-dam irrigation system in the world; and a wonder in the development of Chinese science. And you can see cultural heritages in the Chuanzhusi Temple.
These two scenic areas are also the most worth places for tourists. Hope you like. :-)
