72 hour visa in Shenzhen, coming from HongKong, going to Shanghai

Hi,

I am now in HongKong, and have a flight from Shenzhen to Shanghai tomorrow. I will leave China from Shanghai the next day (to Amsterdam). I intent to take the bus to Shenzhen airport. Can I apply for the 72 hours free transit at the border between HongKong and Shenzhen?

Thanks in advance!
