Kung Fu star Jet Li has made a rare public appearance in Hong Kong to attend a star-studded charity gala on the opening night of Hong Kong Fashion Week.

The 52-year-old action star was accompanied by his good friends, film producers Charles Heung and wife Tiffany Chen.

Li was diagnosed with hyperthyroidism a few years ago.

And he has scaled back his acting career and has instead been focusing on his charity organization, One Foundation.

He had a recurring role in the "Expendables" franchise, appearing in the third film in 2014.

Other celebrities attending the gala included fellow Kung Fu star Donnie Yen and Ray Lui.
