Because we don't know when the drama will finish. Most of the titles, at the end have some express packs with x last eps in one day. And meanwhile, depends what else will drop, sometimes it's two eps, sometimes one per day, sometimes we have breaks for variety of reasons etc. So that's why on many pages, finishing date is blank, to not edit it constantly.
I asked them if they are going to air the full series or only the ones that iQiyi already aired, but I didn't…
It's hard to tell, but at least we have some source for the drama , because IQiyi removed it completly. But most of the time, they air titles , full one, but sometimes it take time, and they are not very fast with updating those ^^"
