144 hour visa free transit in Shanghai and Beijing

I will take the first cruise from Tokyo to Shanghai. On the way, the cruise will stop in some ports of China, such as, Hongkong, Xiamen.

I will take the second cruise, on the same ship, from Shanghai to Tokyo, but his time the ship will stop in Tianjin (Beijing) for 3 days, and in Dilian before going to Tokyo.

Can I get a 144 hour visa free transit to Shanghai?

And then, when i arrive Beijing, can I arrive Beijing, can I get another 144 hour visa free transit to Beijing?

Thank you very much for your attention.
Sincerely,
Can Vo
