Ouyang Xiu, a great writer in the Northern Song Dynasty, summed up the reading method of "counting words every day and reciting them every day" according to his reading experience. He chose ten books, such as The Book of Filial Piety, The Analects of Confucius and The Book of Songs.
About 50,000 words, and then it is stipulated to read 300 words every day, and all of them will be read in three and a half years. Reciting the word 150 every day takes only seven years.
