I think having lived in london my whole life i will just act as if i am still here - although i am sure its much safer there given we have about 5 break-ins a month in my local area. I dont really care about the “stuff” as long as there is minimal risk to my personal safety.
I can't speak for other villages but villages in Lung Mei Tai Mei Tuk area are pretty good.
My neighbour warned there was 1 burglary just before Xmas, cause we were going away, but that's the only one I've heard of in 1.5yrs. Not claiming there aren't more but people generally look out for each other and you get to know people even if just by face.
We're lucky to live in a nice cluster of homes where we know all and many are friends. We all look out for each other. Nearby the 'auntie' a kind Hakka lady has made Pun Choi for our neighborhood and we were even invited to local Chung Yeung celebrations, where we were provided a feast with nothing asked in return (unless you count having to swallow shots of baiju , which appeased the village elders).
For us poorly trained dogs and their shit are one of the few downsides of village life. Yes there are conflicts, if you're an owner you can have issues with the rather complex web of land distribution, but as a renter you'll likely not be bothered by this. However make sure if you have a car that parking is written into lease and properly defined.
Love sipping coffee on the roof every morning looking at the mountains and sea, listening to birds chirp....
