Check your tickets again. My flights earlier this year were RMB 190 total = RMB 50 ACF + RMB 140 fuel. The only exception was a shortie I did from Beijing-Elianhaote which was RMB 130 total (50 + 80). I have never seen/heard of a domestic ticket this year with a fuel surcharge of RMB 190 by itself. Although I didn't deal with any really long flights such as BJ-Urumqi where maybe there was a third level of surcharge.
