2.5 & 2.6 part in Chinese Tourist Visa Application

My flight bound for Shanghai is Dec 4, 2019 and arrival is Dec 5 at 12:05AM and then my flight back to the Philippines is Dec 8 at 1:35AM. My question is how many days is my intended stay that should be declared in my visa application (2.5), is it 4 days? Also, in 2.6 part of the visa application form (Travel itinerary) should i include Dec 8 by then i'd be checked out from my hotel and i'd probably be in the airport already coz the flight sched is 1:35AM.
