A 3 hour overage between arrival and departure

I have booked my flight from Bali arriving into Shanghai at 7:20 am and could not get a flight out on the same airline on the Wed morning flight before 7:20 am (72 hours later) and thus booked a flight leaving from Shanghai on the same airline into Hong Kong at 10:20 am Wed...and this I am technically 3 hours over 72 hour arrival and departure times....will this three hour difference stop me from getting a landing visa and should I simply leave the night before.
