Profits and losses are ignored.

"Fu Lei's Family Letter" is the best book for art apprentices to cultivate themselves. It is also a book about teaching children full of father's love, and it is also the most influential family motto in modern China. Fu Lei and his wife are role models for Chinese parents. They let their son know "the honor and disgrace of the country and the dignity of art" and become an "artist with both moral and artistic skills and outstanding personality." It is inevitable that there will be setbacks in life, but there will also be successes. Just like what Fu Lei said in his book, "Gains and losses should not be taken into account. Victory and defeat are commonplace in military affairs." We must have a heart of "Don't be arrogant in victory, and don't be discouraged in defeat." Face the challenges in life.
