The implication of booster failure makes no sense at all.
Less sense than the Chinese intentionally dropping a booster with a bunch of hypergolics on board in a populated area, well outside of their published notams? Within view of a luxury resort where people would take pictures and post them on the net?

All existing long-march series vehicles have almost identical first and second stages, differing only by slight engine variants or tank stretches. But the Chinese performed a launch the day after this test! That's not enough time to even find the cause of a failure, nevermind fix it.
That depends on the failure. It might have been obviously connected to something specific to the test.

An obvious possibility is a fairing failure  - if the (very mission specific) nose crumples, the rocket is toast but
it's clearly not a rocket issue

How much commonality is there between these rockets; they are manufactured at two locations? Also fairing failure did not stop a CZ2E?

A1782 seems not to be related to A1783?

this paper has a few info of hypersonic vehicle shapes tested in China (even including some wind tunnel model pics): The stability analysis of rolling motion of hypersonic vehicles and its validations

Was there a Chinese space launch May 23?

http://www.wantchinatimes.com/news-subclass-cnt.aspx?id=20150526000061&cid=1101
On May 23, internet users from different parts of northwestern China including Ningxia, Shaanxi and Inner Mongolia said they witnessed an unidentified flying object in the sky, with many suspecting it to be a new spacecraft or missile, reports state-run Global Times. The event took place the night of May 23.

ADD Five photos..

No videos. Still might be an a/c contrail.

Sounds like a missile test to me given the list of places, and that the contrail seems to be towards the NW. Someone might check the NOTAM for that day to clear things up.

Nothing new about this event?

3 zone closures on the 20th pointing north-west from TSLC - I presume that this isn't spaceflight related.  ;)
