However, auxiliary words are meaningless. This sentence is equivalent to "Chu Youcai", and "Wei" does not simply correspond to "Wei".
As for "Si", that is what it means here.
From the 17th to 22nd year of Jiaqing in Qing Dynasty (1812-1817), Yuan was the head of Yuelu Academy. The master asked him to write a couplet, and Yuan asked the students to respond with "only Chu has material". Just as he was meditating, your respectful name Zhang Zhongjie arrived, and everyone said, "Prosperity is thinking". This famous couplet was written in this way.
The first part of the book Only Chu Youcai was published as Zuo Zhuan. The original sentence is: "Although Chu is talented, Jin is practical." The second couplet "Xing Yu Si" comes from The Analects of Confucius, Taber Sheng Yu Si. The meaning of all-in-one machine can be understood as: Chu is really a place where talented people come forth in large numbers, and Yuelu Academy is a club where talented people gather.
