The event at the Qingdao Guoxin Stadium marks the final time the IJF World Tour competition will be held in the Chinese city as it is moving to Hohhot, the capital of Inner Mongolia in North China.

It is also the penultimate tournament of the season, with the last event of the campaign scheduled to take place in 2020 Olympic and Paralympic Games host city Tokyo from December 2 to 4.

A total of 155 judoka from 15 nations are set to compete at the event in Qingdao, where Yu, winner of a bronze in the over 78 kilogram competition at Rio 2016, is one of the headline names due to take to the mat.

It will be her first appearance at a major event since the Olympics and she is the top seed in her category.

World Judo Masters silver medallist and team-mate Ma Sisi will be one of the athletes hoping to spoil the homecoming party for Yu, with Zagreb Grand Prix bronze medallist Sandra Jablonskyte also likely to be in contention.

She comes into the competition as the favourite having finished seventh at Rio 2016.

Ulaanbaatar Grand Prix winner Sai Yinjirigala, who competes at under 73kg, is also on the Chinese team for the competition in Qingdao.
