Under (such circumstances) (… 之下)

Structure Circumstance (disyllabic) + 之下，result

… 之下 (… zhī xià) is a fixed, formal nominal closing: it marks the circumstance or state of mind UNDER which something happens. Unlike 在…下 (HSK 5), the context is EMBEDDED right before 之下, with no 在 at the start, and it almost always forms a fixed two-syllable block: 情急之下 ("in the urgency of the moment"), 无奈之下 ("having no choice"), 一怒之下 ("in a fit of anger"). It is written and narrative in register, common in journalism and storytelling; it sounds more literary and compact than 在…情况下.
