There are few buses from Hechuan to the University Town. You can take the bus from Shapingba, then take the No.249 bus from Shapingba to the University Town Heavy Normal University, and get off at a distance to get to the Medical University. Or take the Beibei bus in Hechuan, and then take the bus to the University Town in Beibei. I can't remember whether it is 565 or 555. Anyway, that line will go to the gate of medical university. If it's no trouble, you can take a bus at Hongqi Hegou Station in Hechuan, then change to Bishan Bus at Hongqi Hegou Station, get off at the gate of Electronic School, and take three rounds to Medical University, probably around 5 yuan. This method is similar to the first one in time. I haven't sat on the second one. I don't know how long it will take.
