Take bus no.52 and get off at the second doctor. It's not in the hospital outpatient department, it's opposite the hospital. If you want to cross the road, you can take the underground passage. Don't take the emergency door when crossing the road, but enter the school gate. The swimming pool is on the edge of the playground. You should bypass the playground and go in. Ask the students inside when you arrive. The charge seems to be per person 10 yuan. I can't remember the details. You can get a discount with your student ID card.
