I repeat my question can I get one visa to cover visits to Shanghai and Hong Kong?

My wife and I are traveling to Europe in October with a 36-hour stopover, not a transit, in Shanghai on the outward flight and a 12-hour stopover, not transit, in Hong Kong on the return flight. We will be leaving the airport during both stopovers. The stopovers are 35 days apart. Do we need separate visas for Shanghai and Hong Kong or can we get one visa to cover both stopovers? I have already asked the question, but you only replied in the case of transit visits. My question was about stopovers where I leave the airport.
