### Chinese: 至于女主明明不是弱智可在某些方面表现的就像个5岁小孩，我真不知道这是演技的原因还是导演的要求。
### English: As for whether the actress is obviously not a weak mind that can act in some ways like a five-year-old child, I really don't know whether this is the reason for acting or the director's requirement.
### Errors: There is a major error of incorrect translation does not accurately represent the correct translation at "obviously not a weak mind". There is a major error of incorrect translation includes information not present in the correct translation at "in some ways". There is a major error of incorrect translation is missing content from the correct translation at "the director's requirement". There is a major error of incorrect translation has stylistic problems at "I really don't know". There is a major error of wrong grammatical register (eg, inappropriately informal pronouns). internal inconsistency (not related to terminology) at "As for".

### Improved English: As for why the female leading role acts like a five-year-old child when she is not retarded at all, I really don’t know if there is problem with her acting or it was demanded by the director.
