Lyrics: Li Shutong (Master Hongyi)

Outside the pavilion, beside the ancient road, the grass is blue?

The evening breeze blows the flute, and the sunset is beyond the mountain?

The horizon, the horizon, intimate friends are half scattered?

Life is rare to get together, only a lot of separation?

Outside the pavilion, beside the ancient road, the grass is blue?

The horizon, the horizon, intimate friends are half scattered?

A pot of turbid water has spilled all the joy, so let's bid farewell to Meng Han tonight.
