Unlikely to occur, but a flyover by a single supersonic capable H-20 could have that kind of effect on certain audiences.
Hypersonic missiles sound scary, but the typical TWZ reader can't meaningfully differentiate between a DF-17, DF-26, DF-27, DF-100 and whatever HACM that may grace Tiananmen Square on September 3rd.
However, a large supersonic (V)LO bomber — with no Western analogue — might "do the trick," in particular as fighters and bombers tend to be topics that Western audiences are more interested in and familiar with.
Not counting on such a scenario to occur, especially as how best to interpret their consensus could depend on how highly or lowly these Chinese commentators think of "Western military fans."
