We must learn to do economic work from all who know how, no matter who they are. We must esteem them as teachers, learning from them respectfully and conscientiously. We must not pretend to know when we do not know.
Mao ZedongA Communist must never be opinionated or domineering, thinking that he is good in everything while others are good in nothing; he must never shut himself up in his little room, or brag and boast and lord it over others.
