Just to add some information to the photos posted by Pierre ..
The top photo is the Chinese-produced Harbin Z-6 which was a turbine 'interpretation' [read reverse engineered] of the Mi-4. Less than 20 examples were built (though reliable information is scarce) as Harbin were unable to achieve any improvement in performance over their Z-5 (see below) which was a Chinese produced version of the Mi-4.
The second photo, as indicated, is an Alouette III and which was part of a small number delivered by Aérospatiale in the 1970's. Licensed production in China was discussed but never pursued.
The third photo is the Harbin Z-5 which, as mentioned, was a Chinese-built version of the Mi4 (aka "The Russian Chickasaw"). In 1979 Harbin fitted one of their Z-5's with a Pratt & Whitney TwinPac but, sadly for P&W, the development went no further.
The bottom photo is the ubiquitous Mi-8.
