In Jining, the newly-built sports swimming pool may be a good choice for swimming training. They offer free courses, and even if students can't swim after graduation, they can make up lessons for free until they learn.

Please note that the above information is for reference only, and the specific swimming pool and course arrangement may change. When choosing a swimming training venue, I suggest you consider many factors, including the facilities of the venue, the professional level of the coach, the curriculum and so on.
