UK, Hong Kong, Shanghai, Cruise to Japan, Shangai, UK, 114 hour - visa?

Hello,
My partner ant I are traveling from United Kingdom to Hong Kong, stay there 2 nights and after that flying to Shanghai, stay two nights and take a cruise of 4 nights to Nagasaki and back to Shanghai, one more night in Shanghai and fly back to UK.

Could we use the 114 hour free transit before and after the cruise, as the cruise leave Chinese waters?
Thank you.
