However, there is such a harmony poem at the beginning of the story of Ping Jia, which you can have a look at. I don't think it's an exaggeration to say the Warring States Period.
The bell of the garden pavilion rings, telling the impermanence of the world.

Pride and extravagance don't last long, just like a dream on a spring night.
Strong beams are overbearing and eventually collapse, like dust raised in the wind.
