Last I heard HNA Group was operating 11 or so different airlines, Hainan Airlines being the biggest. They operate 73's, 76's, A330's and A340's. HNA Group is the biggest privately (mostly) owned airline in China. The top 3 are gov't owned.
Between all the airlines HNA has:
CRJ's - ERJ's
EMB170 and 190's
And A319's, A330's and 340's
73's and 76's
Some of them are Tianjin Airlines, Lucky Air, West Air, Grand China, Capital (Deer) Air, and a few more... Hope this helps.
