Do I need to fill out "itinerary in China section" in the VISA application form?

My company just got employment license and invitation letter for me. they will pick me up I might stay in a hostel for two days then will shift to an apartment. Should I fill in hostel details? (I'm not sure about this)

These itinerary details are just mandatory for tourists, right? Since my longest intended stay in "000" (as per invitation letter), this might not be a mandatory section to fill in, right?

Anyway, this is my first time to other country. it'd be great if you could share insights.

Thanks in advance.
