Xiaoyu Combo thread. (since the forum where I usually get the combos is unorganized in the xiao section I just have add the ones I use ._.)

*SS+3
...B+3 RDS 2, 2, 2, 1, ff+1, B! ff, b, f+3, 1, 1+2.
...B+3 RDS 2, 2, 2, 2, B! f+3+4, 3+4 The end of this string is my fav. It's very useful against players that haven't seen it. After the f+3+4 3+4, you can follow up with a f+3+4. By that time you'll be right in front of your opponent in RDS. From this you have many options for a combo reset. If they backroll use RDS 4_RDS d+4 (RDS 4 almost always hits if they back roll, even if they're hold back xD), if they just stand up you can use RDS 4_RDS d+4_RDS 1+3_RDS 2+4, if they side roll RDS d+4 or use the grab that goes with the side they roll to. After a while they'll just lay there or do a low wake-up kick. You can parry the low kick from RDS with d/f+1+4.
