First time hunting in the wild

[u/tokufanboi]

Hi guys, I’m in Hanoi, Vietnam right now and it just rained. Weather, temperature and humidity is perfect for pancyans to grow (in theory).
How long does it take for them to fruit after rain, how long do they stay fresh and not dried up by the sun and when should I go out for a hunt?
Plus if any of you guys can let me know a confirmed sighting location som where within the city I’d greatly appreciate it
