Lin Dan brought the curtain down on his two-decade career in the Chinese national badminton team. “From 2000 to 2020, that’s an entire 20 years ... As a veteran (老运动员) of nearly 37 years of age, my physical strength and injuries will not allow me to fight with my teammates anymore,” Lin wrote on Sina Weibo last month. It evoked nostalgia (怀旧) about his splendid achievements, including two Olympic gold medals, five world championships, five Sudirman Cups and six Thomas Cups. Responding to Lin’s retirement, many celebrities paid tribute to (向......致敬) the great player including his frenemy (友敌) – Malaysian player Lee Chong Wei. “Please believe that all the laughter, tears and promises are an unforgettable diary. My greatest opponent (对手). Proud of you,” Lee wrote on Weibo.
