此物由来不可名。
丝纶收去水波平。
长抱膝，可怜生。
谁共蓑衣卧月明。

赏析：
The poem describes something that is beyond description, its origins unknown. The image of silk threads gathering and calming the water's ripples evokes a sense of tranquility and peace. The act of hugging the knees symbolizes a lonely and pitiful existence. The final line raises the question of who shares the same straw cloak and lies under the moonlight, hinting at a desire for companionship and connection.
