Select the first option. It's a short walk. You get off at Chen Jiaping, cross the overpass, take bus No.468 and get off at the terminal, then you will see the road where the light rail turns upside down. Go there and you will see the school gate. Walk for about 10 minutes.
The second option is actually better. Because of the Caiyuanba, the school has a new student reception. As long as you find them, you can take the school bus to school, and all the procedures for admission will be guided.
