What is Song Taizong trying to cover up by compiling books and compiling history all his life, and what is the reason behind it?

Friends who are familiar with Song Taizong must know that Song Taizong was born as a military commander, and his education level was average, but he liked reading very much. It is well known that "reading is beneficial" originated from Song Taizong. Song Taizong has made many outstanding achievements in sorting out ancient documents in China, and even wrote his own books. Then the question is, why did an emperor like him bother to compile books? I think there are several main reasons.

Song Taizong himself likes reading very much.

Song Taizong once said, "I like reading, which is very interesting. Opening books is beneficial. Is it in vain? " I naturally like reading, and I can also feel the pleasure of reading. As long as I open the book, there will always be some benefits, and reading will never be in vain. Over the years, Song Taizong's famous saying has touched many scholars. So judging from his words and deeds, he should be a person who likes reading very much.

Song Taizong is actually secretly changing history.

Among the books edited by Song Taizong all his life, the most striking one is Mao Shi Lu, which he personally presided over and examined. On the surface, it is concerned about the cause of the late emperor, but in fact, in order to ensure his own throne, he deliberately deleted the relevant historical materials that were incorrect for his accession to the throne. After all, during the reign of Emperor Taizong, Song Taizu and Song Taizong's younger brother had many sons. When I do something bad, I always want to wipe my blood clean. However, all kinds of cover-ups by Emperor Taizong were nothing but shattered glass, which made people laugh at later generations.

In fact, I think the second possibility is more likely, because he is considering his own reputation, which is for sure. Whether he likes reading or not can only be guessed.
