Who put Sansheng under the fence and shed tears and scattered acacia?

Who put Sansheng under the fence and shed tears in the air means sad tears.

20 12 There is a passage on the Internet: Who is holding a broken pipa in the middle of the night? Who treads lightly in the ink, holding colored threads to embroider empty flowers? Who put infatuation under the fence and shed tears in the air? Who is full of melancholy to write years of life, and who is far away from the horizon to preach hate and false oath?

This is a passage from Acacia Bites Your Tears.
