The 21-year-old San Antonio Spurs star is in “closed-door martial arts training,” an employee at Shaolin Temple in central China told NBC News.

Victor Wembanyama is in China, and it’s not all about vacation. The San Antonio Spurs star is in the midst of what’s expected to be a 10-day stay at a Shaolin temple in Zhengzhou, China.

As part of an offseason excursion to China, the 7-foot-4 Spurs center is taking part in a 10-day retreat at the 1,500-year-old Shaolin Temple. Photos of Wembanyama, 21, with a newly shaved head circulated on social media this week, and the NBA’s China office confirmed that the Frenchman is at the Buddhist temple.
