Confucius said, "isn't it pleasant to review exercises often after learning?" Is it not delightful to have friends coming from distant quarters? I am not disgusted or angry that others don't understand my theory. Am I not a noble gentleman? "
Ceng Zi said: "I saved three times a day and was unfaithful to others." Don't believe in making friends? Can't you learn? "
Ceng Zi said: "I have to reflect on myself many times every day: Is it loyalty to give advice and help others? Are friends trustworthy? Have you reviewed the knowledge taught by the teacher? "
8. Confucius said, "Reviewing the past and learning the new can be a teacher."
Confucius said, "Only by reviewing the past and learning the new can you become a teacher."
