Does Beijing 144 hour visa free policy apply?

Hi - my husband and I are landing in Shanghai on 31 January from the UK and depart from Shanghai on 3 February on a cruise ship touring for 14 nights ending in Singapore on 17 February. As we are only in Shanghai for a few nights I understand that there is a 144 visa-free transit available for landing in Shanghai, is this correct and if so what is the procedure for this?

I look forward to hearing from you.
