i need to arrive to Pudong airport , then need to get next flight from Hongqiao Arpt,

You can take airport shuttle bus line 1 to Hongqiao Airport. It takes around an hour on the way. And the ticket fare is CNY 30 per person.

If you arrive in the peak travel season (07:00-09:00 and 05:00-07:00), it's more advised to take Maglev Train to get to Longyang Road first. Then take subway line 2 to East Nanjing Road and transfer to line 10 to Hongqiao Airport, Exit 1. In this way, you won't get stuck in traffic jams. The wholeway takes around 65 mins.
