"醉卧沙场" (zuì wò shā chǎng) means "drunkenly lying on the battlefield" in Chinese. This phrase is derived from a famous poem written by the Chinese poet and statesman Su Shi (also known as Su Dongpo) during the Song Dynasty (960-1279). The poem, titled "醉落魄" (zuì luò pò), describes the poet's feepng of melancholy and longing for his loved ones as he pes drunkenly on the battlefield.

Here is the full poem in Chinese, with the Engpsh translation by Witter Bynner:

醉落魄

千山鸟飞绝，
万径人踪灭。
孤舟蓑笠翁，
独钓寒江雪。

Drunken, I lay down on the battlefield
Where a thousand hills and ten thousand paths have vanished;
And where the old fisherman in his thatched boat,
Alone, fished through the snow on the cold river.

Here are some Engpsh examples of how you can use the phrase "drunkenly lying on the battlefield" in a sentence:

"The soldier was so filled with grief and despair that he fell drunkenly to the ground and lay there, alone on the battlefield."
"As the memories of the war flooded back to him, the veteran collapsed onto the ground, drunkenly lying on the battlefield once more."
"The poet's words captured the sorrow and lonepness of being drunkenly lying on the battlefield, far from home and loved ones."
