Either you're very wrong on that or you should inform The General Station of Shanghai Immigration Inspection (GSSII).
"The GSSII and and its affiliated immigration inspection stations are the main authority to implement the 144-hour visa-exemption transit policy" [for Shanghai].
And on the GSSII web site there's their press release mentioning ...
In a comparison with its previous incarnation, the 72-hour visa-exemption transit policy which came into effect on January 1, 2013, this latest 144-hour visa-exemption transit policy represents breakthroughs in many areas and boasts many eye-catching aspects. First and foremost, the length of time for visa-exemption stay is extended considerably. With the previous 72 hours doubled, foreign passengers would have ample time to conduct short-term activities such as businesses , sightseeing, visits and exhibitions while in Shanghai.
