Return flight with same final destination but stop over in Shanghai

Dear All,

I have a question here, can I enjoy the visa exemption if I fly KUL-PVG and then less than 72 hours after I would do KUL-HKG and HKG-KUL bought as a one-way trip PVG-KUL. So it is a round-trip in terms of final destination but not exiting Shanghai to fly back straight to KUL and using another airlines. Thanks in advance for your feedback on this.

Regards.
