横看成岭侧成峰,远近高低各不同.不识庐山真面目,只缘身在此山中.
It's like a range
when you look at the mountain from the front.
But it's like a peak
When you look at it sideways.
The mountain shows its different features
In different levels near and far.
You don't know the real Lushan Mountain,
Because you are in the mountain yourself.
