Third, the design of investigation questions, investigation questions should be simple and clear, touching people's hearts, avoiding using imprecise words, avoiding asking conclusive questions, avoiding leading questions, avoiding sensitive topics that embarrass the respondents, and avoiding multiple solutions to one question. Each question has a clear purpose, which ensures the quality of information to the greatest extent. Words should be concise and questions should be fluent. For example, "Do you often get sick?" "How many times did you get sick last month" or "How many times did you get sick in the past six months?" . "Where were you born?" Avoid using these directional words "often" and "some".
