永远的北京结，曾经的迎客松 Farewell, beautiful pine tree! Thanks for nothing, careless, idiotic hikers!

The wonderful pine tree that has stood on top of the Beijing Knot at Jiankou for years is reported missing.
It died a few years ago, and that can't have been helped by the kind of posing done on the tree as seen in this Chinese article. Even if you can't read Chinese you can get the gist from the pictures.
Such a shame.
