Otter has probably hinted at a potential new/next-generation SL-ICBM test in the Bohai Sea area later today (6 July), though he has swiftly deleted that Weibo post.
He deleted it because he was mistaken; he must have made an assumption based on the new NOTAM, but it was probably just a rocket launch.
And thanks to you, he will surely get a tea invitation now, potentially even some jail time.
Stop being such a drama queen. Making assumptions based on publicly available information like NOTAMs and navigation warnings won't get you invited for a tea.
I'm really annoying people like you. Even though you know nothing about OSINT, that doesn't stop you from using it to intimidate others.
