As I was flying to ZZZ; right about over MHT [VOR]; I encountered continues moderate turbulence at 6;000 feet; I requested to climb to 8;000 feet; as I was climbing ATC advised me that larger airplanes had reported moderate turbulence between 6;000 and 8;000 then; when I got out of the clouds at 8;000 feet; for a brief moment it got a little better; but; when I got in the clouds again; it got very aggressive turbulent again; the airplane made abrupt movements; life jackets coming loose and over the cabin; safety briefing card flying around and the passenger getting shacked back there; immediately I requested descent to 6;000 and then to 5;000; then at 5;000 I saw ZZZ airport; requested and got the visual approach and landed.
