Trammell will be a strong rival. He is very fast in the first 30 meters.

Two doctors are responsible for his recovery, and it goes very well.

We will decide how to prepare for the Moscow world championships according to the influence of the ankle injury and the condition of the recovery.

There are more than three weeks before the Moscow world indoor championships on March 10, so it will not affect his competition there.

For Liu, the main goal for the National Games is to ensure a gold, rather than chasing a better result.

The World Cup is one of the three most important athletics tournaments only after the Olympics and the world championships. And Athens is Liu's lucky place, so we will try our best to get a good result.

Liu will make new breakthroughs in Beijing, doing even better than 12.91.
