Yun's ground crossup vs air

This is more of an anti-Yun question - but which way do you parry when Yun tries to cross you up with a F+HP while you jump in? He seems to get you with the back of his attack from behind. Is there any timing issues here I should be aware of? I have had a lot of trouble parrying this for some reason.

Just parry it the way as it shows.
he hits you from the left you parry left.
