: This study was not medical research nor regarded human experimentation as stated in the Declaration of Helsinki. Moreover, all the respondents were 18 years old and over and informed consent was obtained from all participants before survey. Also, the investigation was strictly anonymous and the collected information was only used for research purposes. Therefore, the Ethics Committee of Jiangnan University deemed the questionnaire and methodology for this study to be exempt from ethical review (without an approval number) in January 2021.
: Informed consent was obtained from all participants for participation in the study. We contacted the companies via email to seek for cooperation, and then selected a contact person in each company that was tested. The contact person was responsible for the distribution and collection of the questionnaires. Before the questionnaire items, we enclosed a letter containing a consent statement and only respondents who agreed to participate in the study would go through all the questions. Thus, informed consent was obtained from all participants before we conducted the survey.
