Any snake that is seen near my house is dispatched ASAP and eaten by the neighbours.

I agree with Brian . If your not the one to protect your home and family then who is ?
We have plenty of snakes in this neck of the woods including a few Kingcobras.
On all occasions of being confronted with a snake the snake has either given a warning im too close or slithered off to pastures new.
Fortunately non have ever tried to enter the house, a full grown monitor had a wander around once , which freaked the Mrs out , but no snakes .
As much as i love a bit of wildlife and respect that snakes are important to the eco system here , i too would evict one from the house and if killing it was the only ,or safest way of doing it , it will be dispatched to snake navarna.

Why lift it over the wall? So it can climb back.

Leave them alone, stamp your feet or bang the ground with something heavy and they will take off.

Our house has a fairly tall surrounding wall and main gate. I can't be certain, but I imagine most snakes finding their way in have climbed a neighbour's tree and come down on top of the wall, or from open land straight through the front gate. I don't recall snakes I've come across previously attempting to climb the wall to escape, rather than going up what bushes or trees we have. But, from your video, some snakes can obviously climb vertically, although I think the one in the video didn't actually make it over the top.
The reason I try to assist the snake over the wall is not to encourage it to climb back!~ but to get it off our property and steer it away from any areas where it could be more of a problem to move eg. down a drain, into the loft. Although, I imagine our property has a lot less places to hide than a typical Thai village house.(We've seen videos of snakes coming up a toilet before now, which I feel certain cures any constipation issues. ) If, as you suggest, it's frightened of me and the two dogs probably snapping at it, I hope it has the sense not to come back again.
As I said, I like to think the dogs are a positive factor, in warning me of some kind of danger. I can see an argument that if the dogs weren't actually trying to bite the thing, the snake might be more tempted to slide off quietly confronted by only a noisy me.

Hi there, since we are talking about cobras, anyone can identify this fella for me please? Unfortunately it is already without the head bit still in piece on the photo( just before it went into Tom Yam Snake;) ). Went inside the house in the farm, and uncle smashed it with large stick, said it was a cobra...

Thanks,
Mike

With the White v shaped hoops i would say its a kingcobra , but all the ones ive seen have been a lot darker with the hoops more distictive . Like a slate grey with a white hoop .
However the size looks about right .
Maybe a juvenile or female.
