Newbie here: Having trouble finding routes with high estimated demand?

[sheeeep]

Hi all, new to this game. Slowly trying to figure things out

I'm having trouble discovering routes with high estimated demand. I am based out of Hangzhou. Using the route planner, I looked in to flying to various major airports, such as Tokyo, Dubai, Seoul, Taipei, Mumbai, etc. and to my surprise they only have estimated daily pax about 100, most are less. Why is that? Is there any other more efficient ways of doing this other than clicking on "Route information" for each and every airports?

Thanks for your help in advance!

hangzhou is not a major international gateway as airwaysim scales somewhat with real life historic data. Majority of your route is within China mainland itself and HKG.
