Fat people look fat, but most of them are muscles that don't have to be angular. If you look at boxers' arms, they usually don't have big biceps, but they usually have broad back muscles. Feiduo's obvious back strength and slightly fat figure also provide good physical help. Moreover, the current fighting field technology (such as Balu Sambo) is very important. This technology has the advantages of being fat, thin and refined, so it is the strongest in the modern arena.
