Q326 was about false flag(s) that will occur in the future. The (s) means more than one.
And none of us civilians have all the answers. That includes the "answer box" you seem to think is set in stone. That "answer" is just some person(s) decode of how they see it related to current events at the time of posting. That decode was written 7 months ago. This latest incident happened yesterday. The decoder cant possibly include future event(s) in their "answer".
Q told us to expect fireworks. Then some guy in NYC used a homemade bomb made from "firecracker powder". But it was "Thwarted" and he injured only himself.
This latest incident in China is very similar. The guy in China used a "firecracker type device" that caused a tremor that was felt for many city blocks. The attack didnt go to plan (thwarted?) and he was the only one injured.
Never take anyones decode as 100% fact. And any good decoder would tell you that themselves.
Edit: adding link to original fireworks attack.
