If you get off at Chongzhou, you can buy a ticket for Jinsha Station at Chongzhou Station, then take bus No.96 or 13 at Jinsha Station (No.96 starts at Jinsha Station and 13 is outside Jinsha Station), and you can go to Jincheng College of Sichuan University. But I suggest you go to Wenjiang first, because Jinsha Station will be closed in a few days. After getting off at Wenjiang bus station, you can go straight ahead for a few hundred meters, and you will see bus No.763, but be careful not to go in the opposite direction. If you have no sense of direction, ask passers-by and you will find it easily. Take bus No.763 directly to Jincheng College of Sichuan University, and it won't be expensive to take a taxi. Some tricycles also have to go.
