24 hr Direct Transit: Flying from Los Angeles to Shanghai to board an Asia cruise within 24 hrs

Hi there, we are supposed to fly to Shanghai, stay one night in hotel, then board a cruise ship the next day for a 10 day cruise to Asia (ending in Singapore, not entering any other China city). If our total stay in Shanghai is under 24 hrs, do we enjoy the 24 hr direct transit policy? Most links that I read cover flights in and out of Shanghai, but not flying into Shanghai airport then leaving city via cruise ship. Thank you.
