Will the 144 hour China visa cover me?

I will arrive by air to Shanghai (Baoshan) 3:pm on a Friday,
depart by cruise ship 8:pm on Saturday to Incheon South Korea,
return to China (Tianjin) on cruise on Wednesday at 6:am
(Wednesday - Friday daytime exploring the area, Perhaps a trip to Beijing)
staying on board ship each night
depart Tianjin on Friday at 6:pm for Jeju Island South Korea to arrive on Sunday

Will the 144 hour visa cover me?

Thank you
