Paris - Wuhan (02:30 stopover) - Hangzhou | 72 Hour free transit

Hello

I wanted to know if i can enter China on the 72 h free transit . I am flying from Paris to Wuhan with a 2:30 stopover and then to Hangzhou. I am in Hangzhou for 3 days and then fly to Seoul.
Would i need to get a visa or can i use the 72 hour free transit ?
