Ding Qiqing

Career Born in Zhejiang, Ding started playing badminton at the age of 9 and joined the Chinese national team in 1981.

Ding was selected for the 1986 Thomas Cup squad. In the final against Indonesia, Ding lost the second men's singles match to Lius Pongoh. Despite this loss, the Chinese national team won the Thomas Cup 3–2. Ding also participated in the 1986 Asian Games, where he won bronze in the men's doubles event and silver in the men's team event.

In 1987, Ding retired prematurely due to a waist injury sustained during training. In 2000, having adopted the Japanese name "Kei Nakashima", he changed his nationality and became a coach of the Japanese national team, following several years as a part-time coach for local Japanese badminton clubs. A few years later, Nakashima coached the prominent Japanese women's doubles pair of Kumiko Ogura and Reiko Shiota, who won five All Japan Badminton Championships titles, the bronze medal at the 2006 Asian Games, and another bronze medal at the 2007 IBF World Championships.

Nakashima's coaching led to further success when Reika Kakiiwa and Mizuki Fujii won a silver medal at the 2012 Olympic Games in London. His coaching efforts culminated in Japan's first Olympic gold medal in badminton at the 2016 Olympic Games in Rio de Janeiro, when Misaki Matsutomo and Ayaka Takahashi secured the women's doubles title. After the match, Matsutomo thanked Nakashima, saying "If the Japanese badminton team did not have him, we would not be where we are today".
