I looked it up on the Internet, and I don't know if you are going to Jinhu or Huai 'an.
You'll know when you get to the bus stop. It is better to have a non-stop flight. If not, you can change trains.
The answer to your question is:
1 2, you can go to the bus station. If there is a direct flight, you can take a bus to Nanjing or Yangzhou. There must be one. When you get to Nanjing Central Gate Bus Station or Yangzhou Station, you can transfer to the place you want to go.
3. Huai' an has a bus to Jinhu, which takes less than 2 hours to drive; If you go directly to Jinhu, you can transfer directly to Jinhu without changing trains in Huai 'an.
The gymnasium is just over the Jinhu Middle School. There is a bus stop in Jinhu. You can take the 1 bus or take a taxi at the station. Probably need 13 yuan. You can directly ask him to take you to the high school of Jinhu Middle School.
I hope it helps you.
