We currently have booking DFW-PVG // HKG-PEK-DFW . We will have separate booking for PVG-HKG.

As per my understanding since we are transiting through PVG to HKG its possible to get 144 hours TWOV at PVG. we were also interested in sidetrip to visit Xian and Guilin during that time. Is it possible to visit those places on TWOV. I am aware there are some regional restrictions but are those really enforced?

We have few others in our group who do not qualify for TWOV and they have single entry visa so entering multiple times is not an option
