56-year-old Jet Li (李連杰) suffers from hyperthyroidism in 2013 and has been taking medicine to control his illness. Since then, he seldom makes on-screen appearances and is taken photographs of looking haggard and in grey hair in Tibet earlier. Thus, Jet resembled a 70-year-old man and the students even called him an old uncle. In 2018, he appeared energetic when supporting the stage play (奪命証人) starring his father-in-law (利永錫) in Hong Kong.

On 30th October 2019, Jet shared photo of Jack Ma (馬雲) and himself in black hair with black spectacle at a charity event on his social media account. It is obvious that he appears younger and there is a drastic difference when compared to his looks in Tibet.
