As for women, Wei Yongli is China’s biggest hope for 100m and 200m races. She's the defending champion, and last month, she broke the 11-secondbarrier in the 100m, clocking 10.99sec.

Though Team China also enjoy an advantage in the men's and women's 4x100-meter relay races, they will face competition from Team Japan. At the 2016 Summer Olympics in Rio, Ryota Yamagata, Shota Iizuka, Asuka Cambridge and Yoshihide Kiryu brought home the silver medal during men's 4x100-meter relay with 37.60 seconds, a new record in Asia. Though Shuhei Tada replaces Lizuka, Japan is still the biggest obstacle in China’s way to the gold. Meanwhile, Yamagata and Cambridge will not make the 100-meter race a cakewalk.
