He wrote: "Badminton bros. I played badminton with my dad every Friday when I was five years old. Now that I have grown up, I still play badminton with my dad on Friday."
Lin, 40, also posted a video of himself in action at the OCBC Arena at Singapore Sports Hub.
His good friend, singer Hong Junyang, commented with a pleading-face emoji. Actor Shaun Chen chipped in: "Bro, let's invite @jjlin and uncle to play next time."
Malaysian badminton star Lee Chong Wei responded to Chen: "You beat me first before playing with @jjlin". And Chen replied: "Wow, bro... it's impossible to beat you."
Lin then suggested to Lee: "You teach me to play, while I teach you to sing?"
Lin was recently nominated for Best Male Singer (Mandarin) for his album Drifter • Like You Do at this year's Golden Melody Awards in August, but lost to Taiwanese rapper Soft Lipa. – The Straits Times/Asia News Network
