The country is in a troubled period, and people are anxious.
Tips
history
From Sun Guangxian's Song-dynasty miscellany 《北梦琐言》: '多事之秋,灭迹匿端' - 'in troubled times, erase your tracks and hide your ends.' Here 秋 means 'season' in the broad sense of 'period,' not literally autumn.
mistakes
Don't read 秋 as the season autumn. 多事之秋 = 多事之时 - the word 秋 is classical shorthand for 'a period / time.' So 多事之秋 applies any time of year.
