Reading is useless. It has been here for a long time. Perhaps the oldest advocate is Zhong You, the proud disciple of Confucius, namely Luz. He once said to his teacher, "Why study and then study?" Write it down in (Advanced). In other words, with people, land (community) and grain (millet), what books are there to read? If you have food, you will "learn". Can books be eaten as meals? This is caused by a person being an official, which shows that the intention of being an official is to learn.
