Wang Chong was an outstanding thinker and philosopher in ancient China. He was ambitious since he was a child and loved reading. But his family is poor and can't afford books at all. Wang Chong likes to visit the book market, but he only reads it but doesn't buy it, because he can recite it backwards once.
Later, he almost regarded the book market in the market as his own study and studied tirelessly in the bookstore all day. Whether it's hot or cold, windy or rainy, he comes to the bookstore early every day to do odd jobs, and then reads with a book in his hand.
He is absorbed in reading and tireless. Sometimes he forgets to eat and rest. The shop was also generous, lending him all the books. He read all the books in this bookstore, went to another bookstore and read all the bookstores in the market. He has accumulated a great deal of knowledge. Later, it took Wang Chong more than 30 years to complete a masterpiece Lun Heng, which made great contributions to later generations.
