Abstract: Light is a main style characteristic of Meng Haoran's poems, which has been prai sed invariably throughout the various dynasties. However, I am trying to talk a bout his poems, not about the light, but his melancholy. Because, besides light , Meng's poems also takes on a little melancholy, just like the worry about his official career, his miss of his friends, his homesickness and his sadness from the past time and some historic things and so on.
