Hello everyone! 大家好!

I am asking for help with completing my questionnaire. Respondents must be native Mandarin speakers from Northern China (Beijing, Tianjin, Hebei, Liaoning, Jilin, Heilongjiang, Shanxi, Shaanxi, Henan, Shandong). Also, if it doesn't apply to you, but you know someone who could complete it, please share it with them.

The questionnaire (link below) is in Standard Chinese (普通话). Thank you!
