Several important things about Jung Ha. First, he was a Muslim. That may seem strange until you consider that by the late 14th century, China had long experience with Muslims, especially when they were ruled by, wait for it, the Mongols. Secondly, Jung Ha was a eunuch. Fortunately, 15th century China had excellent general anesthesia, so I'm sure it didn't hurt at all when they castrated him. What's that, Stan? They didn't have general anesthesia?
