In terms of the tool kit, I think it's probably very difficult to find the perfect or the right tool to examine people's implicit inner discrimination. Once incidents happen, this implicit sentiment becomes explicit, so we need to pay particular attention to the effects of these kinds of incidents, racial incidents, and examine these cases and see how they are related to people's implicit sentiments.
That's why I suggested the government should set up a team to keep an eye on social media and know what's going on, what's being heatedly debated in the community, and to detect any language and sentiment early on and to examine the reasons behind it, to nip it in the bud.
