Three hundred Tang Poems

If you can guarantee that your "300 Tang Poems" is genuine, not because of piracy, then it is normal that the version is different from what you learned in middle school. The main reason is that the printing of ancient books caused mistakes because of the knowledge level and typesetting of the printers, while the ancient times could not be corrected by the authors because of poor communication, which led to the spread of errors and the emergence of different versions.

So it is difficult for modern people to read and understand. Today, people have to determine which version is more likely to be the original correct word according to the meaning of the text. Therefore, middle school textbooks choose the most likely correct version, and other versions still exist. That's what you said.
