Pagan eyewitnesses testified that some of the Orthodox met death with astonishing self-sacrifice. The Orthodox catechist Paul Wang died a martyr's death with a prayer on his lips. The Mission school teacher Ia Wen was tortured twice. The first time, the Boxer rebels chopped her up and covered her half-dead body with earth. When she regained consciousness, her groans were heard by the (pagan) watchman who took her to his guard's booth. But after a while the Boxer rebels seized her again and this time tortured her to death. In both cases Ia Wen joyfully professed Christ before her torturers."^[59]
