Ancient and modern sages (reading Du Wen)

If you know what is going on in the world, you must read the books of ancient and modern times. If you learn it, you can use it everywhere. Daoguang is not necessarily equal to zero. If you can't learn, ask if you don't know; Reading depends on self-care, and the teacher is just a guide.

Good songs are never tired of singing, and good books are never tired of reading. Reading is expensive in doubt, and doubt can teach. Reading silently is easy to think, reading aloud is easy to remember. If you start reading a good book, you will get a good friend; Rereading a good book is like knowing an old friend. Pay attention to all knowledge everywhere, and agree that there is a teacher in the line.
