Montpellier, like the Paris Olympics, is something special cos' this is where live the most pro-EU people, those are both Socialist Party strongholds, this party is 100% pro-EU. So they don't care what country from Europe you are, they will support you to death. Specially if it's against China, Russia or Argentina (in many sports argentinians have made their motto to sing racist chants against France, if they don't win it always end with provocations and/or brawls of all sorts) .
About Fan Zhendong, my poppa chubby, my favorite chinese player ever, we all can guess he's now out of the CNT and training way less than before. He said at multiple occasions he was a bit overwhelmed by all the negative attention he received from his own compatriots, be it in social media, being stalked in his everyday real life, and so on. Seems that Europe, and specially Germany, is the best country and continent for him to live his best life: no pressure from people when he goes outside, can go watch football matches with his friend Timo, can go to pop music concerts without having to feel accountable to his compatriots. When you're a football pro of course it's a bit different, but that is probably the only sport you can feel pressure from your compatriots in Europe, but that's mostly in England with the tabloïds. Germany, Spain, even Italy are way cooler with their football pros.
