But the centre yet holds?
Literally: thing – emotion – noisy – “in that way”
Alternately: Widespread unrest and turmoil. Something, especially society at large, in a state of upheaval, disturbance, convulsion, and kerfuffle. Even if you’re reform-minded, not the best way to live.
Notes: This is another combination of two two-character compounds. 物情 is popular sentiment. 騒然 is a state of disruption and instability.
