Cheung chau mozzies n snakes etc
Plenty of mosquitoes here; chiefly around dusk, and dawn if you’re up and about then.
Various poisonous creatures: centipedes perhaps worst for propensity to bite people (when bump into them, maybe in dark), tho painful rather than lethal for adults. Also various snakes around: you can be glad of street lights thro woods to the peninsula! Myblog on this site has more re wildlife, esp birds.
Occastionally, tropical storms halt ferries; but rare for ferries to halt without most of Hong Kong also coming to a halt (as typhoon real close, say).
Yes, a top place to live; top views from Seascape too, I think.
