This is my translation.Would you like to correct my mistakes? Thank you very much! Is there any standards to valuate the meaning of one's life?It's evident to put forward an absolute standard.However, on the whole, it's not really hard to make a porper judgement through whether one has serious attitude toward his life and how he treats to his work and lives.From ancient time till now,all the people who have achievements,are very serious about their life.They always try to work hard and study more and never dream of their time and spend time in vain. In every danisty of our country,the huge labours,great politicians and great thinkers are all the same.
