Margaret, but it is hard to answer you properly because we do not know the nature of your itinerary.
If your entries into Shanghai are of the type:
UK - Shanghai - Japan
You do not need a visa because you will be covered by 144 hour visa free transit.
If your another entry is Japan - Shanghai - UK
You also do not need a visa because you will be covered by 144 hour visa free transit.
It is just important that the immediate points before and after Shanghai are in two different countries or eligible territories (eligible territories are Hong Kong, Taiwan and Macau).
So, all the wisdom is based on the immediate points before and after Shanghai. If they are really in two different countries, then you do not need any application in advance and any visa and any embassy.
However, if you are not certain and have a hard time to handle this visa free transit schemes, then you will apply for a double entry visa online and after that definitely visit the Chinese embassy or consulate to collect your visas.
I would advise you to present us here your detailed travel itinerary is order that we tell you with certainty if you are eligible for 144 hour visa free transit, so that you are free from obtaining any visa in advance.
