What is the fastest way to go from pudong to hongqiao, how long it will take

I think the fatest way from Pudong Airport to Hongqiao Airport is taking a taxi. It normally takes around an hour but the cost is a bit high, about CNY150-200 per cab. There are also other options for you to choose, one is to take airport shuttle line 1 at a cost of CNY30 per person. The ride takes around one hour and 20 minutes. The other option is to take subway line 2 and you will get to Hongqiao in around an hour and 40 minutes. To save time, you may also consider taking meglev train from Pudong to Longyang Road (8 minutes) first and then transfer to subway line 2 to Hongqiao. Hope the information helps.
