Which poem was written by that author? What is the whole poem?

"Horizontal silk to vertical silk" comes from "Folk Songs" edited by Feng Menglong.

No love words, no poetry,

One party, Supa, knows.

I know my voice is upside down.

Horizontal silk is also silk, and vertical silk is also silk.

Who knows such worries?

Supa is made of silk, two-way "silk", full of acacia, reverse "thinking"?

I can't write love stories or poems. When I miss my lover, I will send a white handkerchief to express my thoughts. However, when the lover received the handkerchief, he did not "know" it, but held it in his hand and looked at it repeatedly. Looking sideways, it was just silk. I couldn't see a word at all, so I said to myself, "Alas, who knows what she is thinking?"

Extended data:

Feng Menglong briefly discusses the characteristics, development history, value and social function of folk songs in Xu, which is an early folk song prose and an important material for studying Feng Menglong's folk literature and art thought. In his comments, he suggested that the arrangement of folk songs should follow the original appearance of folk literature works, which is of great significance to the collection and compilation of folk literature. This book has reference value for studying the development and social life of Jiangnan folk songs in Ming Dynasty.

Folk Songs is an album of Jiangnan folk songs collected by Feng Menglong in Ming Dynasty. This book is a small collection of folk songs that records the Wu dialect areas around Suzhou in the Ming Dynasty (including Suzhou, Huzhou and Jiaxing today). Suzhou folk songs in the late Ming Dynasty objectively retained a lot of Wu vocabulary, which is of great value to the current study of Wu history.

Folk Song has been lost for a long time. 1934, the owner of Baoyutang visited Huizhou and got the original book. After proofreading by Gu Jiegang, it was published in 1935 with a preface.
