Eight Fingers Zen, a Zen master in modern times, was named Jing 'an, and the common name was Huang Dushan. He was the first president of the Chinese Buddhist Association, a famous poet and monk in the late Qing Dynasty, nicknamed "Eight Fingers Zen". 1877, when Jing' an was 27 years old, he burned two fingers in front of the stupa of Ayurveda Temple in Ningbo, and cut off his arm to burn a lamp for the Buddha, hence the name "Eight Fingers Buddha".
