To ensure the accuracy and quality of our survey results, we do not allow corrections in most Le Yan She surveys. If members were able to restart a questionnaire, they might change their answers, especially if they are already familiar with the questions. This could lead to inconsistent responses and affect the overall results. For this reason, it is also not possible to go back and change answers once a questionnaire has been started.

While this might result in a few minor mistakes, please don't worry and continue participating in surveys. Our algorithms are designed to maintain the overall reliability of our survey data.
