I don't remember, because the military training was unified by the whole school when I was a freshman, and it lasted until the National Day.
Then I had a holiday. When I came back from the holiday, the swimming pool was closed and only open to students of the Institute of Physical Education.
Remember that swimming lessons are only open to sophomores. If you want to swim, you can buy your own ticket directly.
Both the College of Ocean Engineering and the Institute of Physical Education have swimming pools.
