Beijing-Qingdao-Beijing with a 144h transit visa possible?

Hey Guys,

I'm planning to attend a sports event in Qingdao and I was wondering if I have to apply for a China Visa or could just fly to Beijing, book a train to Quingdao for the event, return to Beijing afterwards and then fly to my next destination. Would I be allowed to book a train ticket to Qingdao with my Beijing 144h transit visa?

Thanks & best,
Chris
