144 hours permit free transit Shanghai

We arrive with a cruise ship to Shanghai from Hongkong, manilla, Japan. 1 night we stay on the ship H.A.L. In Shanghai.
After that we stay two day's in an hotel in Shanghai.
1. Do we need a permit/visum to Travel from the ship in to Shanghai?
2. Do we need a permit/visum for entering/stay for two day's in Shanghai?
3. Can we use the free transit periode of 144 oure on the moment we arrive with the ship in Shanghai.
