Man... machine translations' got a lonnnnnnng way to go.
Translation:
A lot of people are asking why choose FC-31? I feel many have misunderstood the priorities. Firstly, it's not just a matter of "J-20 vs FC-31," the carrier's requirements are for a medium aircraft; every time I've mentioned 4th-gen carrier-based fighter, I've always said "medium aircraft." I don't know how the J-20 and FC-31 will be modified but whichever is modified better to fit the criteria will be adopted. It's a competition between how well the modifications are implemented; the merits of the existing J-20 and FC-31 are of secondary concern. Secondly, how are you guys able to immediately jump to conclusions that the FC-31 modifications have already succeeded? Yes, SAC is working double time on the modifications but that is no guarantor of adoption. The ultimate decider is whether the PLAN is satisfied.
