Mr. Liang Qichao's speech "Dedication and Happiness" explained people's attitude towards occupation in a simple way and discussed the importance of dedication and happiness. According to his own personal experience, Mr. Liang pointed out that "responsibility", "benefit" and "appointment" and "happiness" are most closely related: "responsibility" means "appointment" and "benefit" means "happiness". He believes that we must have a sense of responsibility in doing things and be good at "appreciating the fun from the profession". A person with a sense of responsibility, interest, dedication and happiness, and dedication to perfection is the "reasonable life of mankind." "A person is disrespectful to his profession. Theoretically speaking, it is a blasphemy against the sanctity of occupation; In fact, you must have done something bad and ended up hurting yourself. Therefore, professionalism is the most necessary and beneficial to life. " Mr Qi Chao deserves to be a wise man. His analysis of the problem is reasonable and thorough, which is very instructive. For me, teaching is a profession to make a living, so I must not blaspheme the title of teacher because of my carelessness and disrespect, so that I lose my job.
