Lol, so many rumors abound here usually disseminated by the "I have omniscient level of inside info" crooners of course, that it's now normal to assume a rumour is true, and I am called a cynic. How did we get to the point where we readily believed a whole spot would be given to a player just on the basis of "maybe he can beat Harimoto for us"?, China's best bet at beating Hari is still Chuqin tbh. He's still the guy who's shown that quality over a lot of matches, not just a one-off thing. So many Chinese fringe players have beaten Harimoto at least once, just based on a quick think; HYZ, XF, CYY, XYB, even NGK lol.
If Xue Fei has Harimoto number and only Harimoto's, makes more sense to have him as a practice partner/analytics team for when the top players play Harimoto. If he can't beat any of the other guys, he's not contributing much to the team's priorities. Unless China would rig a heavily scrutinised and live streamed draw, then I don't see how this assumption doesn't fall apart. But we could always find someone who has a story known to him alone certainly.
