The suggestion letter that Zhou Shijie mentioned was a rose-red foldable letter that looked like an invitation letter.
However, the words 'invitation letter' were written on the front of the invitation letter, while the words 'suggestion letter' were written on the front of the 'suggestion letter'.
The suggestion letter was even simpler. There was only one sentence and two options.
That sentence was,"are you satisfied with this personal cooking exhibition? if you are satisfied, please check if you are satisfied. If you are not satisfied, please check if you are not satisfied." Below this sentence were two options: satisfied and dissatisfied.
These words were written in both English and Chinese. At the end of the suggestion letter, there was a reminder that signatures were not required.
Yes, this suggestion letter was a completely independent and transparent vote.
