The error of "can neither play nor sing" is generally divided into several categories such as missing subjects, improper word matching, reversed word order, inconsistency, and incomplete components. The mistake in this play is obviously the subject, who (in ancient times or modern times) can neither play nor sing, so it can be changed to: In ancient times, there were only written records of this kind of musical works, and there is no music score information. We (today) Can neither play nor sing.
