Transit visa for stopover in Hangzhou?

I am a French citizen, will be travelling from Sydney (Australia) to Beijing with a 3 hour stopover in Hangzhou, both flights with China Eastern Airlines. Then I will stay in Beijing for a little more than 24 hours and will then fly to Paris with Air France . All my flights are booked and confirmed :
- do I need a transit visa in Hangzhou?
- do I need a transit visa in Beijing
