In fact, many people don't know that there are more than 3,000 poems handed down in the Spring and Autumn Period, and only 3 1 1 is included in The Book of Songs. Why did the Book of Songs only include 3 1 1? First of all, the reason for 1 is that there are more than 3,000 poems left over from the Spring and Autumn Period, many of which are not well preserved. Over time, many poems have been lost before they are included, and their shadows can no longer be found.
Another reason is probably that many of these more than 3,000 poems are not well written. As we all know, the Book of Songs contains many folk songs from all over the country, but many folk songs are not very good in content or other aspects, so they can only go downstream.
When the ancient editors received the Book of Songs, they would take part in the screening for many times, and select the better ones among these more than 3,000 poems, that is to say, take the essence and discard the dross. Also, if these more than 3,000 poems are included in The Book of Songs, the workload will be too great. Perhaps the editor has also considered this reason, so he can only include the essence in the Book of Songs.
