I arrived at pudong airport, shanghai at 5 AM. How can i go to putuoshan from there?

You can take airport shuttle bus line 7 to get to Shanghai South Railway Station first. The service hours are from 7:30-23:00.
Then walk to South Bus Station and take a coach to Shenjiamen Putuo Bus Station directly. The bus schedules are from 06:55 to 19:29 with the ticket fare of CNY 130 to 220 per person. It takes around 5 hours on the way.
After that, take a taxi to Banshengdong Wharf and take a ferry there to get to the mountain area.
