Ya but is that any different than Beijing? The Chinese government has to keep the propaganda and slogans up everywhere, it’s really the only tool they know of to communicate broadly their apparent successes to the people.
It actually was, both in sheer intensity and in style. For example, in Beijing (at least when I last visited) it was kind of hard to find posters of Xi Jinping, while in Lhasa you had a lot of this kind of thing: https://imgur.com/a/GRN9VZz
Which to me seemed remarkably tone deaf (nothing like reminding Tibetans to celebrate their "liberation" and its mastermind Mao), but presumably worrying about how the message would land was not among the KPIs of the cadre responsible.
