The original words are like this. Comrade Mao Zedong has a famous saying in "On Practice": "The issue of knowledge is a scientific issue. There is no need for hypocrisy and pride. What is decisively needed is its opposite - honesty and humility."
I tried to translate.
The matter of knowledge is a serious matter so that one can't be false and arrogant. The real need is the reverse side - the honest and the humble manner.
