The statistics you use are a little suspect, as the first ambassador killed in the line of duty was in 1950. Given that, using the founding as the total time for your average isn't really sensible.
Your major point still stands, however, that embassy attacks are not unusual - since 1971 there has been on average a little less than one a year, it's just usually the casualties are absorbed by civilians and the security of the host nation so we don't pay as much attention.
I never said it was barren, I said it was dismal. Went back and looked again. First thing I notice is how the entire image looks washed out by smog. They have hundreds of identical apartment blocks, separated from industrial hell by a half-assed canal. On the north side they have what looks to be slums. Apparently they have parks. Half the place looks like it might have been made yesterday, which I assume it was. Still not impressed.
Lest you think I'm biased against China, Ordos to the south looks like a much nicer place to live. though I gather it has its own issues.
Always draw your curves, then plot your reading.
