Where can I recruit swimming coaches and piano tutors (girls at school)?

Piano is in Shijiazhuang University (formerly Normal College), Art College of Hebei Normal University, Shijiazhuang Art School, Hebei Art College, Swimming Coach, Water Park, Sports Team, Sports School and Normal University. You can check or post on their websites. If you want to find an intern, you can call the school directly and ask the teacher to recommend it or go directly to the school! The students in these schools are very willing to practice. I am also looking for a piano teacher.
