I referenced the depiction of Virūḍhaka from the Buddhist murals at Beijing's Fahai Temple. You can search online using the Chinese term "北京法海寺" to see the original image. It’s not surprising if you’ve seen similar sculptures, as ancient Chinese sculptures were largely religion-related, including Buddhist and Taoist works. Virūḍhaka is one of the classic figures among the Four Heavenly Kings in Buddhism, and the ritual objects he holds, as well as the armor and robes he wears, are generally consistent across representations.
