Happy Birthday, Lin Dan! You're officially another year older—but don't worry, your legendary smashes and lightning-fast reflexes are timeless. Just like fine wine or a perfectly executed shuttlecock drop shot, you only get better with age!From dominating the courts at Beijing 2008 to repeating Olympic glory in London 2012—your epic victories have left opponents breathless (and probably still chasing after that elusive shuttle). May this birthday bring as much joy as those unforgettable gold medal moments.
Keep smashing life's challenges just like you've smashed badminton records. Here's wishing you endless happiness—and fewer sore muscles tomorrow morning!
