Live from 2017 TechCrunch Shanghai, where we kick off with the classic TechCrunch hackathon! Brought to you by TechNode and TechCrunch, this edition of the hackathon has 300+ contestants and 66 teams.

The teams need to come up with innovative solutions in 24 hours to three challenges from BMW and Citic, the sponsors of the event, or have the choice of coming up with a custom challenge. Esteemed members from the Global 500 will be judging and 13 winning teams will be selected.

Join us as we document the hackathon over the next 24 hours. Check back for regular updates!
