Just a few days after Xie Zhenye ran a 9.97 seconds to shatter the Chinese record, Su Biantian ran 9.91 at the 2018 IAAF World Challenge Meet in Madrid today. Before Xie Zhenye, no Asian man had ran a sub-10 seconds. In just the past few days, now two Asians are sub 10 seconds runners.
NAAAAAAAAAAAAAAAAAH, the 2 9.99 second performance of Su Bingtian in the IAAF Diamond League/Prefontaine Classic 2015 and IAAF World Championships in Athletics 2015 were within allowable wind assistance; the former was +1.5 m/sec, and the latter was – 0.4 m/sec.
And the 9.98 seconds record for Yoshihide Kiryu was also within allowable wind assistance of +1.8 m/seconds.
Or else, why you think 9.99 seconds was Chinese national record before it was shattered by Xie Zhenye’s 9.97, and now become Su’s new 9.91 seconds ?? Japan’s national record for 100 meter dash is also Yoshihide Kiryu’s 9.98 seconds.

I think those were wind-assisted and didn’t officially count as sub-10 seconds.
You were dead wrong to write “Before Xie Zhenye, no Asian man had ran a sub-10 seconds.”
Su Bingtian had 2 consecutive 9.99 seconds back in 2015; and Japanese sprinter Yoshihide Kiryu 桐生祥秀 ran 9.98 seconds in 2017.
