A high trust government usually reflected on people's behaviour and general society. You do not need a poll to say your citizens trust you. Paradoxically, if you get a survey in China asking if you approval/disapprove of the government, they will say approve and if anyone been to China you will know why. Talking about the government in China is a rabbit hole you don't want to go down on, especially if you are non-Chinese looking expat.
Polls are meaningless in China, the same attitudes during the Gang of Four (四人帮) still exists today. If Xi was ousted today, the opinion polls will change from 95% approval ratings to calling for his execution.
We seen this During the later stages of the Cultural Revolution, Chinese citizens continued to exhibit strong support for the Gang of Four and the Cultural Revolution. It is likely that if a poll had been conducted at that time, their approval rating would have been close to 100%.
However, following the events of the October 1976 coup, the Chinese people once again rejoiced and celebrated coup and death sentence (which was changed to life imprisonment later on) of the Gang of Four. An eminent writer, Guo Moruo (郭沫若), who had previously expressed admiration for Jiang Qing just a few months earlier, found himself criticizing her within the same year.
This pattern of shifting loyalties and public sentiments was not unique to this period alone. In fact, prior to the rise of the Gang of Four, similar instances occurred involving prominent figures like Lin Biao (林彪) and Liu Shaoqi (刘少奇).
Considering I lived in Chongqing for 3 years. Lots. However I kept my politics extremely private. From 12 years to now I saw China slowly turning into a black hole information.
